Plenty of time for setting up speed traps, but few checks on who gets to fly their expensive toys. Whoops.
Personally I'm surprised that a PPL could fake such knowledge unless he is already very experienced. It's hard to feign knowledge of flying different aircraft when you are actually put to the test. I find it hard enough sometimes remembering how to fly machines that I have trained on properly!
Don't expect Flying Lawyer to get involved in this one.
Client confidentiality may give him a good reason (or excuse!) to keep below the parapet on this one.
