Re: So, since 1961 ...
"By contrast in the UK we just banned semi-auto rifles - no dicking around about whether it was in a wooden stock or a polymer stock, as if that makes any difference to the terminal ballistics of a .223round."
You say it didn't work - I can recall the last mass shooting in the UK - but mostly because a couple of jobs ago I was sufficiently close to the ESN that I had work to do that directly related to it.
That was many years ago... tell me again that our firearms restrictions don't work?
The list of US mass shootings is broken into small groups of years, and split between schools and non schools... The list for the UK is three items, that difference is not accounted for by the comparative size of the countries or populations.
