Discharging firearms to the common danger is an offence, even if not a very serious one.
E.R. Punshon – The Dark Garden (1941)
It's a quote from a work of fiction of course, but here in the UK, the general attitude towards firearms does seem to have undergone a significant change almost within living memory.
Firearms have always been taken seriously of course, but over time, what we regard as serious can change, as our general attitude to firearms seems to have changed. Or perhaps our attitude has been changed on our behalf and behavioural psychology does work.
