Gun buyback programs are spectacular failures. I don't think there's been a single public policy study that's shown it to be effective. And that's with a lot of them being people wishing they would find results.
Especially in the United States now that gun people are flocking to them to outbid the state's offers and buying them instead. Especially with people who don't understand what they're selling.
Forced seizure and regular searches is the only way to go to pretend you're preventing gun ownership outside the elite classes.
Meanwhile, easy things like criminal justice and policing reforms, drug rescheduling, firing everyone in the DEA, etc. let's ignore that. We should definitely focus on trying to repeal the 2nd Amendment or get the courts to gut it further.
Gun "debate" is like abortion. And welfare and immigration. The symptoms are confused for the problems and then people just want to cover up the symptoms best they can and consider the problem solved.
Thankfully, we'll soon have Trump to handle our problems and our symptoms for us.
