PD vs. SD vs. CHP

[Notorious]

Really? Are they stationed in certain DMV offices??

I wouldn't know. All I saw was at a LE conference seeing them set up a table and there were 2 guys in blue polo shirts and 5.11 khaki pants with badges on their belts. Their table display and banner said DMV investigators, no mention of CHP anywhere.

Really? Are they stationed in certain DMV offices??

Yes, but not every office. In Orange Co. they had DMV investigators at the Fullerton, Santa Ana, and one of the So. County DMV's. Some are also at some of the state buildings.

... DMV had their own separate arm of LE with their own DMV investigators?

Yes.

DMV investigators are the real LE arm of the DMV, specializing in stolen vehicles, phony registration and ID rings, etc.

Along with the vehicle code enforcement activities, CHP also took over state police activities upon the absorption of the former CA State Police, like state gov't protection of personnel (the Governor) and state buildings.
