With all due respect finding a wallet in your car after it has been stolen is no proof that the owner of the wallet stole you car (wallet could have been stolen too)- without further corroborative evidence it would not get a conviction. You would hope, however, that it would give the Police cause to fingerprint your vehicle and interview the person.
It’s the lack of action that annoys people most of the time even if the Police can’t make a case.

Then other times, they get very involved and try to set someone up, anyone, to be the perp(s).
I'm surprised they didn't accuse the girl and her granny of an inside job to get insurance money and that they were working with the thieves but turned them in because they didn't give them their cut of the pawn money.
