That was shot in a country with rational gun control laws. They have the lowest handgun ownership level in the EU, at 1%. If you want to own a gun, you have to have an actual, provable reason for it. You also have to take a psychological evaluation, which has to be repeated every 5 years. They have 1 handgun death for every 400,000 people. The US has 1 handgun death for every 10,000 people.
I'm not too worried about the dog.
