Hey man, I’m future you. I here to give past me a warning. You keep looking like a complete fool and when you look for evidence to support your false claims, it turns out you were wrong the whole time, so you built a time machine to stop yourself. Anyway, the warning is to only use 1.11 Jiggawatts, as you miss the return time to stop yourself from looking foolish by about a day. Good luck!
And if my car was in an unrelated accident but just happened to fit those criteria, you could use that as evidence against me (and not only that, but then stop trying to solve the crime because you’ve assumed the perpetrator.) It ALWAYS goes both ways. If the only way you can solve a crime is by violating people’s privacy without a warrant, maybe don’t be a cop.
Cops are seen as bad guys because people like you argue for why rights shouldn’t apply to people, and making you get a warrant (aka doing your job) is seen as interfering with a crime.
The worst part is, it is stupidly easy to get warrants here in the US, but the cops WILL make your life miserable if you make them get one.
