We do things differently here. As a result, we have only had one mass shooting incident in the last 20 years. Our per-capita murder rate is about 1/4 that of the US. We had three fatal police shootings last year, one in 2014 and none in 2013.
You might not like it, but we do. Our system of gun control is overwhelmingly popular.
I don't want to make it another gun control debate, but I do not think it is the prohibition of weapons that make shooting rares. Drugs are equally prohibited and are by no mean rare. Everyone has an assault riffle at home in Switzerland and I have never heard of a mass shooting there. I think it's more a behavioral thing than a gun law thing.
A drug dealer cannot legally import automatic firearms into the US.
The only way they could be imported is by a licensed dealer, for sale to the military or law enforcement.
It's likely you just meant to make a more generalized comparison of the laws, but most people wanting to import the weapons in that article into the US would need to smuggle them.
