Every life that is lost is a tragedy to those involved, whether it's buy a firearm, or car wreck.
The incidents listed above are presented without any stated purpose or frame of reference.
To add a frame of reference for discussion, I have listed some other causes of death and their average daily rate.
The US is a very large place with lots of people.
A list of 10 specific tragedies in a nation that has 5,500 deaths per day adds little to the debate.
By way of comparison, on the same day (on average), 35 people died of liver damage from alcohol abuse, and 54 people died as a result of accidental falls.
We as a society should adopt measures to reduce the risk of death by accident, disease, and all forms of homicide, not just gunshot.
The question is, what measures to adopt.
Some argue that restricting access to handguns will reduce homicides, but it has not been shown to work in US cities that have tried that approach, such as Chicago, or DC.
Some also argue that Chicago and DC law don't work well because nearby jurisdictions do not restrict access to handguns.
Whether this is true or not is up for debate, but until every state adopts Chicago type laws the point is moot.
Since states are free to craft their own laws, it is very unlikely that handgun restrictions like those found in Chicago will ever be passed in all the states.
Many places, like New Hamshire, or North or South Dakota, who enjoy low homicide rates (rates lower than Canada, the UK, Australia), who have a long tradition of gun rights will not be likely to change their laws to please Chicago or DC.
That just leaves federal laws, which is not even capable of getting enough votes to reauthorize the Assault Weapons ban, let along restrict a whole class of firearms, such as handguns.
Simply put, there is not adequate interest in expanding Chicago's and DC's unsuccessful laws to the national level.
