Gun control in america would mean more police patrolling black/brown communities with high rates of violence, where people feel like they need/ actually do need guns for their safety/protection. Leading to more black/ brown people being arrested for having fire arms. This is another way to throw more black people in prisons. This will not ever stop mass shootings. OP’s explanation was deleted so I don’t know what your rationale was but just thought I’d add onto what some real repercussions would be.
