""No prosecutions are to be brought against previous tenants for any crime.""

Why don't you contact your local police, and tell them your theory on precisely which former resident was responsible for which individual piece of vandalism?

You seem to have great difficulty with the notion that prosecution follows on the acquisition of that inconvenient little stumbling block known as evidence, and that a miscreant can only be prosecuted if said evidence supports the conclusion that HE is responsible for the criminal action.

Unfortunately for you, there is no place in our judicial system for a charge of being in possession of an offensive ethnicity, and lynching gypsies out of hand sort of lost its appeal about May 1945.

I'm afraid you may just have to live with the fact that a man is innocent until PROVEN guilty, and that the police cannot act on YOUR opinion as to guilt.
