There are lots of things that people use to kill other people. A lot of people seem to object to the guns, rather than the killing.
In the bloodiest battle in history, Hannibal's assault on Canae, something akin to 70,000 lives were lost in a single day. And not a gun in sight.
The most murderous single act in history, the destruction of the dikes on the Yellow River on June 5 and June 7 in 1938 is claimed to have resulted in 900,000 deaths. The dikes were destroyed with explosives, and water did the rest.
The 1-2 million killed in the Rwandan Genocide were mostly dispatched with machetes. I could go on.
That said, I don't think that guns should be left out so that toddlers can kill their family members, that people should be allowed to shoot up Chevy Dealerships, or that, as seems to be happening in Enid, Oklahoma, people should drive around shooting windows out of passing cars
There seems to be a sentiment here that "gun control" will solve everything, but the common element in all of these atrocities is not gun ownership, it is a willful, murderous intent, and gun legislation doesn't regulate that.
