Would the Police even act on items tagged with smart water? My experiences with Police and theft are that they provide crime numbers for insurance purposes and norhing else. I had an obvious break in attempt on my house 10 years ago. They tried to get in through the conservatory, prying a window corner to shatter it, then realised we were in and scarpered. Tool marks on the frame were obvious but the bobbies reported it as likely someone throwing a rock over the fence (no rock and tool marks!). After pointing this out 3 times I calmly asked whether the bobby had sh!t for brains or whether they were trying to keep the crime figures down - he almost arrested me for it. A burglar was caught 8 doors away in the act, same mode of entry an hour agter I noticed our window and the bobbies dodn't think to compare my frame tooling marks to his tools used on the other place.
