This is a point that's probably very obvious to many Americans, but something I hadn't really considered about the second amendment and the like is that freedom is kind of zero-sum: a consequence of the right to bear arms is that armed guards might have to be stationed at schools, and that cops treat everyone like a potential armed criminal. This last shooting will probably not lead to a meaningful change in gun-control, but it will create pretexts for this administration to crack down on certain political movements.
