Bloody police!

There are things in life that make one lose faith in the powers that be in a country. The potential fraud case that I reported to the Police, being one of them.  I was told by family members of the person I believe defrauded me that I am not alone in this experience, all I am asking is the police to chat to those family members to see if they can illuminate their comments to me and if that helps them establish that the potential defaudster really has had a pattern of this behaviour and if so whether that helps them establish what happened in my case. But despite asking the police to do this over and over they refuse.  I know if my son was accused of having done something I might be interviewed at some point, so why in this case is it deemed to be against data protection for the police to talk to his family.   I give up, the police say that they do not use the internet evidence and that it goes against Data Protection to talk to his family.   How the bloody hell do they ever find evidence if they are not allowed to talk to the people who might be able to shed a light on the situation?     Meanwhile I still have not had my money back.    But the actions of the police is as distressing as the actions of the potential criminal at this moment, because my rare contact ( a year or so since they have bothered to reply to my emails) brings no solice.     Blooody furious.
