Like in Selco’s case the gun laws are pretty strict and its still easy to get your hands on an AK47. People will always find ways to hide their precious possessions and in case of the US, owning guns is such a part of the culture that I guess every little town would have an underground gun smith like Mr. Red said.
You can even produce guns with 3D printers now… as long as people want to own guns they will. I’m not on top of the gun debate in the US but did the moves of the government in recent years to make gun ownership harder have any real effect?
