WASHINGTON (AP) A person briefed on the Boston Marathon investigation says the explosives were in 6-liter pressure cookers and placed in black duffel bags.
The person says the explosives were placed on the ground and contained shards of metal, nails and ball bearings. The person spoke on the condition of anonymity because the investigation was ongoing.
The person says law enforcement officials have some of the bomb components but did not yet know what was used to set off the explosives.
President Barack Obama said Tuesday the bombings were an act of terrorism but investigators do not know if they were carried out by an international or domestic organization, or perhaps by a malevolent individual.

(15,031 posts)there are backpacks aplenty all over a marathon course. Many runners pack their sweats and other personal items in bags which their friends and loved ones carry to have ready for them when they finish the race. Can't say for certain that's the case in Boston, but it's what I've witnessed in every race I've run here in California.

(24,461 posts)Backpacks and gear among the race's 15,000 participants were everywhere, including at the finish line. I imagine this could have just as easily happened there. Who'd have imagined that pressure-cooker bombs would be in a bag among hundreds you just walk by at random?

(15,031 posts)bags the Marathon organizers provide to the participants for their belongings until after the Race. These were all clearly marked as part of the Marathon, and were stored in a roped-off area. But yeah, there are bags everywhere around a large race. My wife used to bring our daughters to watch me finish, and she always packed drinks and snacks in a backpack. I'm sure there were times she set the bag down and left it unattended.
I guess what both you and I are getting at is, we can't anticipate every contingency. And to radically disrupt our lives in fear of the unforeseeable isn't the way I want to live. Nor do I suspect there are many who, in sober reflection, would agree to give up enough freedom to attain such security, especially as it would no doubt be an ephemeral safety, susceptible (again) to the forces of the unforeseeable.

He gave all of us kids a severe talking to about never fiddling with the pressure cooker when he was cooking with it. Can be dangerous if you don't know what you're doing.

(135,425 posts)The cooking in that country in some regards is similar to Indian/Pakistani food, and they use them a lot there as well. You can fire 'em up, heat the stuff up inside, and then take it off the heat and let it depressurize gradually.
They are great kitchen tools if, as you say, you know what you're doing! Paying attention is a big piece of it all, too, of course!

(67,103 posts)adventurous watching the thing in the store. Her stove had one that sunk down into the stove ... and all you saw was steam flying outta the top of the stove ... as I recall something used to pop up and then she would flick a lever on the top of it to release the pressure.
She was really good at using it ... used to use it almost for every meal. The vegetables were really good. As I recall she used to cook certain types of meat in it too. Now, my curiosity is up, we might just try one of these again... I like the idea of using less energy ... and also saving time. Sounds kinda fun!
freshwest
(53,661 posts)It had a chrome top grill in the center and a built-in crockpot in the rear left hand side. I bet that would work as a pressure cooker with the right top on it.
The knobs, handles and everything else was the same. The oven on the right was what provided the heat for the broiler underneath it. The left lower door was a drawer but the upper left door was an oven for warming, with part of the rear space used by the crockpot.
We didn't have a built-in pressure cooker, just the insert and top. My dad used a large Mirro pressure cooker for cooking pintos and making a pot of sauerkraut with polish sausage. My stepmother never would cook that. So it was his late night cooking thing that I found strange and exotic.
It would hiss and rattle angrily although I don't think the new ones are noisy. I darted in and out of the kitchen waiting for it to explode or the round device to fly off and hit something.
Fagor sells two kinds, a pot and a skillet which use the same top and seal. Naturally it has cookbooks and instructions.
There was one significant thing different on our stove. It had a chrome overhang across the top that had a lamp in it. So that the kitchen was never dark at night. Also it was gas and the pilots never went off, quite common in those days.
My dad was into retro things, it was an antique even then, I think. I still miss my dad. He died just before his 52nd birthday in February of 1965.

(135,425 posts)We had an old Rayburn (and I'm talking OLD) that ran on oil--it heated the house, the hot water, AND it cooked the food. Cosy old thing! I wish we could have taken it with us, but it weighed as much as a car~!
It looked a bit like this:
freshwest
(53,661 posts)And I fully believe it heated the whole house. That one I posted about had 6 gas pilots which burned all the time.
Although my dad was modern about some things. Our kitchen had an automatic dishwasher, rather rare in the early fifties, and we had central heat and air conditioning throughout the home. I miss that house, too...
I understand about the weight. Things were more sturdy then and seemed to last forever.
I hope we don't get sent back to the Cooking and Baking galley for going off topic, LOL.

Is a Crock Pot the same as a Pressure Cooker?
Trillo
(9,154 posts)Crock pots cook food at atmospheric pressure slowly at relatively low temperatures for a long time (which is why meat turns out tender).
Pressure cookers are sealed (with controlled steam release), so as heat is applied, the pressure builds up, raising the pressure food is cooked at (under pressure, boiling point of water is raised). These cook food faster, as the pressure "presses" the heat as steam into the food. They're also called pressure canners, and are used to preserve foods, such as in a Ball or Mason jar (or a metal can, often called "retorting" , so the foods may be stored for months on end without the electrical costs of refrigeration or freezing.

(16,191 posts)Pressure cooker bombs were also used in the Times Square bomb a few years ago. I have no idea what the source of the bombing style is, but it's a common technique seen in Pakistan and Afghanistan, and almost nowhere else.
arcane1
(38,613 posts)That seems like quite a leap. Perhaps this method was chosen simply for being cheap and effective?
Xithras
(16,191 posts)There's a bit more to building an IED than simply throwing some explosives and nails into a backpack. The US military teaches some of its soldiers bomb building techniques for improvised warfare (ever see Saving Private Ryan? Remember the bomb, sock, and grease? That's one example). Russians teach their soldiers different techniques. AQ in Iraq had specific bomb building techniques that they used against our soldiers there, that are also now widely seen in Syria. The Taliban have specific bomb making techniques that they teach in their camps.
How a bomb is made can tell you a LOT about who built it.
The pressure cooker technique is widely used in Pakistan and Afghanistan, and is seen almost nowhere else. It was used in the train bombings in Mumbai, which the Pakistani Taliban took credit for (and which was traced to them anyway). Similarly, it's one of the bomb building techniques used in the Times Square attempted boming a few years ago. That was similarly traced to a Pakistani American, credit was claimed by the Pakistani Taliban, and the bomber admitted that he'd been taught bomb building techniques in their training camps.
It's a signature weapon design. It's a great, big, fat arrow pointing back to the Taliban. The Afghan Taliban have never shown much interest in striking the U.S. directly, but the Pakistani Taliban has not only professed an interest...they've tried it before.
There are no logical leaps here.
Sunlei
(22,651 posts)They need to catch the person who placed the bombs.
MADem
(135,425 posts)Authorities are now saying that the explosive devices in Boston were fashioned from pressure cookers. Yes, like the kitchen pot you might use to cook rice at home. As it happens, pressure cookers have a nefarious reputation in counterterrorism circles. In 2004, the Department of Homeland Security was concerned enough about pressure cooker bombs to issue an alert to federal and state security officials: A technique commonly taught in Afghan terrorist training camps is the use/conversion of pressure cookers into IEDs, the bulletin warned.
That bulletin cited several plots from 2002 to 2004 to use pressure cooker bombs in France, India and Nepal. But more recently there have been at least three other instances of would-be terrorists in the west, all of them Islamic radicals, in possession of pressure cookers for reasons that seemed not to involve having friends over for dinner. One was an Army private linked to the 2010 Fort Hood shooter Nidal Hasan, who had reportedly been taking bomb-making tips from the al Qaedas short-lived (literally) magazine Inspire and had various weapons and explosives along with his cooking pot. (The magazine reportedly recommended pressure cookers as explosive devices.) A 2010 suicide bomber in Stockholm had rigged a pressure cooker bomb that failed to detonate. And as a newer DHS warning about the kitchen devices noted, the failed 2010 SUV bomb in New Yorks Times Square was a pressure cooker device featuring 120 firecrackers. The same DHS memo refers to a March 2010 bombing with a pressure cooker at a western Christian aid agency in Pakistan that killed six people.
Counterterror officials are surely well aware of these facts and studying any related leads. But its important to bear in mind that the ability to make these bombs is hardly unique to al Qaeda and its sympathizers. Members of at least one prominent white supremacist website have shared terror tips from Inspire, which one called highly recommended reading. Pressure cooker bombs are also discussed in detail on this anarchist site, which describes how to build what is affectionately known as a HELLHOUND.
...The identity of the Boston bomber or bombers remains very much unclear, and it would be foolish to jump to conclusions. It would also be foolish to ignore the twisted recent history of the pressure cooker as a method for killing innocent people.

hack89
(39,171 posts)it looks like they used gun powder, which is a low-explosive ie it burns slower and creates pressure slower than a high explosive. By using a pressure cooker, the pressure in the vessel is allow to build up to an extremely high level so that when the cooker finally bursts, there is much more energy released all at once.

(14,779 posts)The main reason he lasted as long as he did (and the FBI was no nearer to catch him, till the FBI agree to publish his manifesto) was he went out of his way to make parts of his bomb, parts he could have obtain from local hardware stores. If he had used such common parts, the FBI could have tracked down to where such items were sold, just by knowing who made the part and how that part was distributed. Ted Kaczynski frustrated those attempts for he made ALL of the parts of the bomb himself, even parts he could have purchased at his local hardware store.
Thus, given the nature of most items, who made them, when, what batch etc, most can be traced without any number on them. You can NOT trace each pieced produced, but you can see where it was made and how it was distributed. If you have more then one piece that can be "Traced" this way, you can often get down to the store the items were sold in.
Thus the FBI will pick up the nails, and anything else in the debris, and try to trace all of them and see where all of them could be obtained. This includes the black duffel bags and the pressure cooker. Collectively this is almost as good as having engraved serial numbers on the ball bearings and nails and what else was in the bomb (including the explosive used).

happyslug
(14,779 posts)That was a lot of work, and why he lasted as long as he did (and that he was a one man terrorist organization helped him stay out of the sight of the FBI). How the Unibomber was able to to avoid arrest is an example of the old adage, "Three can keep a Secret, if two of them are dead". With the Unibomber, he was the only one in his network and thus was impossible to catch for that reason. This group does NOT have the intelligence of the Unibomber and they are to many in this terror cell for them to avoid being found, the FBI should be able to track them down quickly.
happyslug
(14,779 posts)I hate to say this, but most US residents who would commit an act of violence tend to be associated with right wing groups who in turn tend to be oriented to the US Military (notice I use the term "oriented" as opposed to associated with the US Military. I use the term "oriented" for most such groups use US surplus or other US military gear in their groups organization, as opposed to be actually associated with the US Military).
I bring this up, for the US military tends to use GREEN duffel bags NOT black duffel bags. Why go out of your way to obtain a black duffel bag, when you have plenty of green ones just laying around?
On the other side, most runners and other people associated with the Boston Marathon tend NOT to be ex-military, and thus were never issued a green duffel bag and thus may have had to buy one, and purchased a black one instead of a green one. This could be seen by some right winger who decided to spend the money and obtain a black duffel bag to cover up the fact he is a right winger AND to better blend the duffel bag with the bomb with the other black duffel bags in the area.
Now, buying a black duffel bag is NOT out of the picture for a right wing group, but given how common green duffel bags are when you deal with military and ex-military personnel, and given the tendency to the right wing groups to imitate the US military, green duffel bags would be a more nature fit for them.
Just a comment that the color of the duffel bag may indicate some group other then a US right wing group.

(14,779 posts)I use a green duffel bag myself, it stands out on an airport baggage claim among all the black suitcases (and is one of the reason I recommend a COLOR suitcase NOT a black one, a color will stand out among all the black suitcases in a baggage claim area).
Thus, a green duffel bag is something most people in those right wing violent group would use, for they have them.
On the other hand, people who observe people at such races will often see other types of duffel bag and want to blend in with whatever is most popular in usage in that area (i.e. does NOT stand out). Thus, by the use of a Black Duffel bag, I can NOT rule out a right wing group, but it is a factor when considering who did this.
It is like the earlier comment about a pressure cooker, the use of which is generally in Pakistan and Afghanistan. If that is TRUE, it is another indication that this is from Pakistan or Afghanistan NOT domestic. The use of a Black Duffel bag implies it was purchased NOT in a war surplus shop (where a lot of US right wingers go for equipment) but a more upscale shop, where someone NOT from the US would go. War Surplus tend to be individually owned, unlike department stores (and even stores like Gander Mountain) and thus a place people from overseas would know of. On the other hand, Gander Mountain, K-Mart, and other stores they could be briefed on and see on the net and be instructed what to buy where,
I suspect the Pressure Cooker and the Duffel bag was purchased in the US, along with whatever was the ingredients in the explosive. Maybe even purchased in the same place (Gander Mountain or Cabelas, or maybe Walmart or K-mart as far as I know). All I am pointing out is the Duffel Bag is NOT the type of Duffel bags most right wing groupies would have.

greyl
(22,990 posts)From this interesting paper:
Terrorism is designed to draw attention to particular issues and causes. Yet, perpetrators often keep their involvement in acts of terrorism secret, resulting in confusion among target audiences. The 1995 Oklahoma City bombing is a case in point. Timothy McVeighs decision to hide his participation in the attack led some authorities to speculate that Islamic militants were to blame (Johnston, 1995). McVeighs silence permitted observers to overlook his message (which was one of frustration with federal police actions in Waco, Texas and Ruby Ridge, Idaho) and to focus instead on other groups and issues.
Given the importance of publicity in terrorist campaigns, why are claims of responsibility issued for some terrorist attacks, but not others?
Claims of responsibility are worthy of analysis because they provide a window into what perpetrators of terrorism want and the incentives that influence their behavior. For example, anonymous attacks are often taken to indicate that groups are disinterested in building grass-roots support for their movements and closed to efforts at political compromise (e.g. Enders & Sandler, 2006). Claimed attacks, on the other hand, are seen as signifying that groups are unafraid of retaliatory strikes (e.g. Hoffman, 1997a,b), which might further imply weaknesses in certain counter-terrorism efforts. In short, credit-taking has the potential to tell observers a great deal about the nature of the threat groups pose and the adequacy of the responses to their attacks.

(11,085 posts)It still makes no sense to me. They don't want to get caught. OK, got that. Yet they want to influence public behavior. The tumult, the furor in response to the attack becomes the goal itself rather than any political message. They must desire the feeling of secret satisfaction rather than the ability to publicly gloat over their actions. How frustrating for them that they can't brag about their most significant act. I'd bet that a lot of them, like serial killers, secretly want to get caught, so they can talk about it.
