For all the joking around, it should be noted that Glasgow, which is notoriously violent with sectarian undertones to go with it, is by some distance the most lethal city in the UK with 3.10 fatalities per 100k, IIRC the only city above 3. Fresnillo tops the list with over 200 per 100k, a killing rate comparable to London during the Blitz. You are 70 times more likely to be murdered in a quiet Mexican city than you are in the UK's most violent city.
