By that logic I should talk to all those people who have had lottery wins to find out how effective it is to play the lottery !
It is human nature to suffer from confirmation bias - we all tend to look for reasons to back up our own belief. What we don't look for is any reason or evidence that our beliefs do not stand up. (Doubly so, I expect in the police service where you are searching for evidence to convict - let the defence find evidence to the contrary)
One example I gave was that of false positives. A search dog indicates on an area - the handler reports this to the search manager. If it was later found the person went through that area, both the handler and search manager remember this incident and use it to back up their belief in search dogs. What they do not remember is the 10 times the dog has indicated on an area that has turned out to be nothing.
But anyway - that all moves away from the question in hand about R&Ps.
PS Thank for the contact. Should I ever get around to doing some work - I will need all the assistance I can get. (Maybe I should stop antagonising you all then )
i give up, or are you trying to wind me up. 22yrs work obviously counts for nothing compared to your hands on experiance and skill.
