This isn't Minority Report. The government cannot preemptively make human beings incapable of murder.
There are a lot of solid arguments against gun laws in America, but "we allow mass murderers to commit mass murder for freedom" is wildly disingenuous and does nothing but hurt the gun-control cause.
@LouisIngenthron I’m sorry, but as anyone observing this issue from the outside will tell you, that’s exactly what it essentially boils down to to a neutral observer. Everything else is noise. Especially when combined with the fact that as long as you only shoot one person, you stand a good chance of getting away with it (as a White person “standing their ground”).
