UK over the years has been destroying something immensely valuable that you can't get back quickly. For example, there are barely any speed cameras on local roads in the UK (compared to other European countries) and yet almost everyone drives under the limit. It's the same with police not needing guns. I think people just don't understand how valuable (and unusual) this is.
Edit: As has been pointed out to me, there are a lot of speed cameras in the UK, but half of them are in the London area where I don't drive (and the rest are mostly motorways) which is why I had that impression.
