But at least they don't have firearms...

Hmmmm sort of! Cranks I might agree with you, except for the fact that it is not impossible to obtain various firearms legally, notably members of shooting clubs and shotguns. I was shocked to see a shop in Barton St Gloucester displaying guns for sail, including (automatic ?) pistols for about 150GBP, in the window. Hardly going to be dummies, might be air pistols but it didn't say so. There were air rifles too.
Barton St has a reputation!

Anyway there are those shockingly young kids guilty of killing, rare but far more shocking because of their lack of responsibility & indiscriminate shooting.

We may feel a bit safer, but there is no room for being smug.
