Unbelievable!!!

my neighbor is away on vacation and is a hard working single parent!   So this morning I noticed a ex boyfriend of hers that hasn't been in the picture for over a year walking into her home!!!  So I called her and let her know what was going on an she was very upset and asked me to please call the police.  So I called 911 and the police came to the location and because the loser didn't change his address in his ID the police could not make him leave or arrest him!!   I feel so bad for this woman. How much more violating can this man be!!!
