In my area, most bail agents are just a step above the felons they're hunting, even ran across one or two felons working as bail agents in my career. One in particular I did arrest, he not only had a prior felony conviction, he posed as an INS agent and threatened deportation to a woman and kids while looking for her brother.
Too bad for him that she was already naturalized and wasn't intimidated at all. She lived in my patrol ward and often acted as a translator for me and my partners, she dropped a dime on him toot sweet. We notified the feds of his actions and they picked him up the second he bonded out of the county lockup. Who says law enforcement can't be fun?
As to the original question, here it would depend on how they portrayed themselves.
If they in any way indicated they were sworn law enforcement, they'd be cuffed and stuffed. Misdemeanor, but as the old saying goes, you may beat the rap but you can't beat the ride.
