not to bring up gun rights but...........
here we go :(
if someone in that building had a concealed weapon this could have been nipped at the bud saving most of those peoples lives.
now the gunman had a gun weather it was legal or illegal it doesn't matter because if you made stricter gun laws people like this would have gotten the gun either way.
criminals get guns illegally if they need them, gun laws DONT STOP CRIMINALS
