A police officer can’t legally commit B&E without a warrant.

That’s why he just made sure the photos got into the hands of other members of the Nation. He effectively allowed the problem to solve itself.

Edit: I just realized that you may not be from the US or be familiar with how the law works here. You need a warrant to do what my father did to the Nation of Islam. None of the photos his took or any of the other evidence would have been admissible in court. He broke the law when he broke into the church.
