Many of those young black males are already banned from having guns, either by age or prior criminal convictions. That banning doesn’t seem to slow them down any more than I think that any new bans would. Criminals will break new laws just as quickly as they break existing ones.
What I meant was not to keep the status quo in terms of enforcement. If action has to be performed, it better be to prevent young black males from using guns. Preventing the rest of the population is not going to solve “gun” violence. It is a “young black male” violence that needs to be solved.
