It's all about politics and very little (actually nothing) to do with reality. Based on available information, we have a solution, but it doesn't fit with the political infighting, as that is what it is all about.
Eliminate the gun free (ha) zones, and have a few of the adults in those areas carry concealed. That will get rid of these high number killings once and for all. I n fact as long as that is NOT done, it is really our reps that are at fault for these murder sprees. They condone, even mandate it, via their asinine laws.
