This is a short diary but this question has not yet been asked by msm.. Where did these animals get their handguns and rifles? In Mass green card holders can acquire a permit with background check and FBI fingerprints. If these killers bought these weapons from a gun show or Internet on the heals of the defeat of the background check bill any senator that voted against has a lot of explaining to do.. The NRA has blocked the ability to track explosives and now once again allow terrorist to exploit the hole in background checks to kill or injure innocent people..
