Currently the police can request to see patient data under 29 of the data protection act. They can only request if it is for a crime or apprehension of a crime. We also have Children act, Crime and disorder act and a few more. but in all cases there has to be application to the data controllers.
Secondly why would they ask for anonymised data when they can go and get the same and better information from the GP's.
