> But if someone stole your bike, usually police wont find it.

That is a "we're not in a post-scarcity society" problem - stolen bikes tend to be below the cut-off point of cases the police can afford to take on. It's not like they have nothing more important to do.

Unfortunately, there aren't many good solutions to this, and the most direct one involves giving even more spy movie tech to the police, so that bike theft case can be solved with a click of a button - but we probably wouldn't want to live in a world where police can actually do that.

Oh they definitely have tools to find who stole bike in city where CTTV is on every corner.

There may be a camera on every corner, but I bet half of these cameras are fake, and most of the rest are privately owned, therefore a huge hassle to get footage from.

the police absolutely found my bike. it had a tracker on it and very distinctive paint.

if you go to them and say "my bike is gone" they'll ask what details you can provide. if the answer is "none" then they're not going to try that hard. hundreds of other missing goods cases too, and many of those could be more than your bike, and have actual leads.
