I don't want Biden doing ANYTHING about this. It isn't his call. Local law enforcement and the courts need to address acts of violence - respond as quickly as possible and arrest the suspect, prosecute the suspect, and incarcerate (better yet, execute) them if found guilty. Government cannot issue prophylactic policies that will even remotely keep everyone safe from every eventuality ... and idiots like Biden need to quit trying to convince Americans that they can ... 'cuz they can't. Life is harsh, sometimes, and there is not one damn thing you can do to prevent bad things from happening - period. The best you can hope for is that the general populace is sufficiently well-armed enough to react to random acts of violence and immediately stop would-be murderers in their tracks.
