The private individual is subject to prosecution for agg assault in that case. Also can be mulcted in civil damages.

You won't find very many actual private citizens who'll do that.

And if they've got some sort of connection to the P.D., they're not a "private citizen". Off duty officers, for example, are still "the State" for Fourth Amendment purposes. I haven't seen a case, but I would think that P.D. employees and contractors would be in the same boat.

Freelance hackers are NOT state actors.

True for the civil end, but the criminal consequences can be waved away with an immunity deal.
