Banning of guns is going to do one thing, increase the value of guns, and create a new black market, which then will only make the criminals more money illegally, this isnt going to stop "gun violence". The only way to keep guns out is to literally have one big wall around the state with checkpoints to check every square inch of cars and trucks to see if they will be imported, if that's what they want give it to them, force them to create their own providence and succeed from the US, as far as I'm concerned it would be on less liberal state
