We may disagree, but I don’t consider collecting evidence as enforcement. Enforcement happens when the regs are enforced with a judgement, which is conducted by the FAA. The CHP cannot issue a judgement upon a party for FAA rules/regs infraction, only collect evidence and report incident to the FAA. Another distinction would be that (as far as I am aware) the CHP is under no obligation to, or compelled to, collect evidence or report infractions to the FAA.
