Even if they were prepared for cyber crime, would they be prepared to act on information you give them? Sure, if you supply law enforcement with the location of your recently stolen electronic device they will go after it (as I've had them do twice now). That's pretty straightforward. On the other hand if you give them the details of some purported fraudster, of whom you are not even a victim, a thorough investigation would be necessary prior to any action on their part. At least I'd hope so, otherwise there's a whole new genre of swatting (i.e. framing unsuspecting victims as black hat hackers) that has yet to be exploited.
