Airspace over Boston closed. Ball bearings found at the scene.

[WilliamPitt]

BPD doing controlled detonations of various. Biden made a statement and used the word "bombs. Cities across the country are beefing up security at landmarks etc.

This was deliberate.

[slackmaster]

1. Deliberate, and probably not the work of one individual

This took some coordination.

[malaise]

2. Wonder if this was an attack on the Sandy Hook families

MSNBC just reported that there was a small IED but she did caution that it is early.

Two people are dead

[HERVEPA]

8. Dumb speculation. Can it!

[kestrel91316]

10. I strongly suggest you apologize to malaise for that remark.

[Bernardo de La Paz]

14. No. It is much too soon for such speculation. The *speculation* is dumb (as stated). Nothing about

No. It is much too soon for such speculation. The *speculation* is dumb (as stated). The poster didn't call the person "dumb".

[randome]

19. What else are you going to do on a discussion forum besides speculate?

[Bernardo de La Paz]

23. Free to speculate, but wild dumb speculation sends it down ratholes for no good purpose.

As to what you are going to do on a discussion forum?

Well, duh, discuss facts, and discuss reasonable theories and hypotheses for which there is some foundation.

[kestrel91316]

22. I'll speculate all I want, and I'll thank you and your RW apologist buddies

to allow me and malaise and anybody else on here to do so without being told to basically STFU.

[HERVEPA]

26. Just as an FYI, your speculation on my political orientation is hogwash

I'm to the left of about 90% of the people on this board. A little fact checking rather than speculation could have told you that.

[Bernardo de La Paz]

38. Leave your personal attacks at the door. No place for them on DU.

Deal with the ideas and concepts and facts.

Leave your personal attacks at the door. No place for them on DU. There are plenty of other forums for personal attacks.

[HERVEPA]

24. I strongly don't care about your suggestion.

Who the hell needs to speculate now.

[kestrel91316]

39. Speculation is our right. If you don't like that little fact,

you are in the wrong place.

[HERVEPA]

40. Thank you for your service to DU.

[HERVEPA]

28. You are certainly welcome to your opinion.

Folks on this board would and gave correctly condemned speculation on other incidents where people would have immediately blamed Muslim extremists. Same should go for our home-grown right-wing extremists.

4. Probably claymore-oriented device.

The blast is bad, but the flying projectiles can kill too. Nasty.

[Katashi_itto]

7. "this is my signature." WHAT DOES THAT MEAN?

[Jazzgirl]

27. Um...the whole last sentence is the signature line

instead of what you are used to seeing.

[Katashi_itto]

35. ok..

[backscatter712]

16. Pipe bomb, most likely. Easy to add ball-bearings for shrapnel. n/t

[Yo_Mama]

5. yes.

Effed up world, to be sure.

[FarPoint]

6. Keep us informed Will.

I have been looking for your posts on this. Thank you.

[one_voice]

9. Forgive my..

ignorance, but what significance do ball bearings have?

[kestrel91316]

11. I think they are placed in an IED to boost killing power.

[jberryhill]

12. ...or from shotgun shells...

[one_voice]

13. Thank you..

was talking to my daughter and that's what we thought.

[atreides1]

30. Here's a little information.

[one_voice]

37. Thank you!

[slackmaster]

36. Shrapnel. In one of the video loops showing an explosion you can see at least one runner reacting...

...to being hit by something. The heat and blast of a shrapnel bomb don't do nearly as much damage as shrapnel.

[smirkymonkey]

15. I'm watching the local news. This is horrific!

I cannot believe this is happening in Boston.

[dixiegrrrrl]

17. and planned to be lethal.

First bomb was inside store, blew out windows in 4 stores, so there is all that glass flying at high speed.
2nd bomb went off further down the block.
Police found and dismantled 3rd boms
wintnesses say they saw " limbs blown off".

Most of the info I have is from constant Twitter stream and videos.

[lpbk2713]

33. If the devices were planted inside stores ...

then there's another source for the perp(s) being caught on surveillance video.

[PCIntern]

21. "welcome to "the" DU and enjoy your stay!" nt

[arcane1]

29. Can we at least wave goodbye to the dead victims before starting with this nonsense?

[WilliamPitt]

34. Shut the fuck up.

[Baitball Blogger]

20. My daughter said they were on some kind of Alert, which, the last time it happened they

arrested 25 people?

[Marrah_G]

31. I'm just so shocked.......and angry.

[Aerows]

41. This is so horrible

Whoever did this not only ruined lives, but they ruined an event that people enjoyed for years to come.

There are some evil, evil assholes in this world. I can't bring myself to call anyone responsible for this a "person". Just horribly tragic .

[Spitfire of ATJ]

42. Doctors are reporting that they are pulling ball bearings out of the victims.
