Mock those who defend the use of the AR15 rifle and argue that it has been used as an assault rifle in various tragic events.
And cue the gun nutters who's biggest argument is the AR15 isn't an assault rifle because it doesn't meet their definition of assault rifle. It looks like another one was used as an assault rifle once more and with horrific consequences. But go on, tell us once again how stupid we are because it's not an assault rifle by your definition.
