Last time i was around Kirkcubright the locals had the road wheels off the tank!
Being serious though, reality is, you have insurance, they’re covered, everything else nowadays is just a mess with bike thefts and so on, i’m just outside Bristol, had a couple nicked about 5 years ago, since then just got proper insurance and made sure it’s not simply a case of walking in and picking the bike up, if they want it, they’ll have to put a bit of effort into it, but if they do nick it, well that’s what insurance is for.
As for the police, it’s a non-violent crime, it’s usually something that has little evidence, and resource is limited for them and when they do catch them, they’re usually out with community service, same thing happens with watch thefts in London and so on, the sad reality is you can’t have nice things and show them off.
