In France we had a case where the government tried to bring terrorist charges against someone, the problem is that the police couldn’t materially have seen what they wrote in their report, because their car was too far and the timing didn’t line up correctly. Eventually the policemen invoked confidentiality rules against their mobile phones so that no accurate probing could be made. The judge threw away the terrorist charges anyways, because the facts didn’t warrant it. Since the police knew exact facts without being there, there is a high suspicion they used illegal spying on the people and tried to launder the data.
