>Is it really so frequent an event?
A long, long time ago, Time Magazine ran an article covering 1 day's worth of guns deaths.
IIRC, it went something like this:
72 deaths - total. Due to accidents, suicides, criminals killing someone, suicide, murder of acquaintances, etc... And self-defense.
4 (out of 72) - number of deaths where criminals were killed by citizens defending themselves. Even assuming those self-defense kills were all justified, the numbers did not really point to guns improving things much.
I really can't see Time ever doing this again. Too hot a topic.
Obama is doing what he can, which is to say, not much. Biometrics are not a bad idea, if they can be made to work, but most of the recent mass shootings have been carried out by the rightful owners of the firearms AFAIK.
