ALL the media is talking about is...
He used a Bushmaster AR-15 ASSAULT RIFLE, USED BY THE MILITARY, TO KILL PEOPLE, we need to ban assault rifles to prevent this from happening in the future.
But the bigger problem is that once again, society is turning to government to make laws that put more guns to our heads. Each law is a "gun". Because in order to enforce each law, no matter how trivial you have to ultimately be willing to KILL people to enforce it. ALL laws are potential "good shoots".
So if you want to make AR-15's, or assault rifles, illegal, you are willing to KILL people for being in possession of one. Not for killing, assault, or committing some other property crime. You are killing them just for being in possession of a gun.
