From what I understand he knew the woman from a previous job he had as a taxi driver. She asked for a ride, and while he complied she asked to pick up a friend of hers. Judging by how the ccw holder conducted himself after the stop I can truly believe that he was naive enough not to put together the hooker + pimp connection. Once again, he put himself in a bad situation, and it's a good lesson to learn to not put yourself in a bad situation. The high light for me is still the officer's behavior during the stop.
