Personally id keep out of it, years ago the police used my home to watch a nearby house for drug dealing, after a week they made arrests. I thought it was all over till the lawyer said my name and address had been provded in court papers, It got a little scary knowing that these guys would know it was my place used to catch them. Fortunately my details were removed. So id keep out of it. If you would not shop a neighbour for cash in hand work or benefot cheating then why bother with something miles away
