I would just like to drop this link to a school shooting that happened not so long ago that everyone has seemingly forgotten about.
http://en.wikipedia.org/wiki/Chardon...chool_shooting
I live in the area, so it jumps to mind whenever I hear about shootings. For those who don't feel like following the link, the shooter used 10 rounds of .22LR in what was the deadliest shooting from 2005 until February 2012. The weapon was either a Ruger MKIII or a .22 revolver. One of the teachers who ended up helping a victim had a bullet proof vest and a HAMMER. I bet he would have been armed if allowed. Those who want to go on a killing spree will always find a way to accomplish their goal. Magazine limits accomplish nothing.
