@ X shooter:
You are certainly right.
In Europe, gun owning is a privilege.
In US is a constitutional right.
In Eastern European countries, it is still considered by public to be the privilege of regime officials. (even worse then in western europe)
For majority of west European countries in reality it means that having a gun is a shared property, divided between real owner and a state. State is a "big brother" in this case which feels free to take the gun whenever he finds good enough reasons, and can do so because the constitutional rights of gun owners are not violated. Because, as mentioned above - it is not a constitutional right in the first place, unlike US.
Though, there are some exceptions.
