What are you talking about? What country in EU ? Because for example here in CZ, there's a lot of firearms. But guess what, you must pay for a gun license and have a doctor examination with possibility of psych. evaluation, then a gun license exam is really hard also practice test of gun handling and shooting is pretty hard and not cheap.

So you will think twice to get it and you really don't want to loose it. Basically turning gun owners into the most law abiding citizens there is.

If you're talking about countries like UK or similar, where you can't legally defend against attackers and biggest cities are controlled by gangs with kitchen knives and acid bottles. Even police don't have guns and can't arrest them, cuz racism or something. GG EZ.
