British police does NOT investigate hacking.
The idea that they do is a myth.
People are told to report cyber crime to the national monitor of cyber crime, Action Fraud, but most people don’t realize that this means that the cyber crime is not actually investigated. The name of the agency sounds so nicely “active” that people fall for it and think that this agency actively investigates cyber crime, but it only keeps statistics and only if there is an economic component.
At some point, I even received a (spoofed) e-mail from Hampshire Constabulary stating that hacking, criminal harassment, business sabotage and shimmying the locks to someone else’s apartment are not crimes. I didn’t bother taking that to the police. It would have been a complete waste of my time.
For the record, what police officers sometimes do appear to do, is tick boxes in their computer programs that make it look like something has been investigated when it hasn’t. (I have proof of that, or at least of police stating to third parties that they investigated something while they didn’t, apparently for no other reason than to discredit someone and suggest that the person was psychotic or paranoid – and I have something that backs up the latter as well. It is the kind of unexpected jaw-dropping information you can uncover when you exercise your FOI rights.)
