I would like to be for more gun control, if gun control means keeping guns out of the mitts of people who intend to go out and do harm to other people with those firearms (gang bangers, angry people intend harm, terrorists, etc).
However, since the current crop of gun control laws don't seem to be accomplishing this goal and the pre-cognitive ability of the human race seems destined for continued failure, I don't see what sort of bonus this failing policy buys our society.
Like it or not, citizens will 99 times out of 100 be the first responders to acts of violence. Their response might be to run away. If out in public with my kids and I hear a gun shot sort of popping sound or see a guy waving a knife, I intend to grab my children and exit stage closest.
Other citizens might run toward the sounds of violence to help people defend themselves or stifle the threat. No telling how people will respond. If we reach the point of gun control where the second group of people can are no longer be effective in their response, then we've sort of over-controlled the guns, in my opinion.
