The voice you get in your head when you own one, obviously.
What surprises me is there is this hyper focus on guns as a way of disarming school shooters and mass murderers. Is there anybody out there that can actually say, "If I owned an AR-15, I probably at one point would have done the same, but thankfully I don't, so I didn't"
How many people out there do we feel are capable, but otherwise unable to commit mass murder? Either because they are not the legal age to buy the weapons, or they can't afford it, or whatever.
