let me also mention that it won't be just a few singular people here and there that have guns it will be organized crime that has guns like motorcycle gangs or drug traffickers, heck they will probably also selling illegal guns and more people who shouldn't have guns will get them. this stuff already happens if its illegal the value of a gun goes up which means people are going to start fighting over gun trade.
which means exponentially more people die.
we don't here this on the news but gangs are still are out there reaking havoc.
