Eric Prince, former head of Blackwater, is a right-wing fanatic. He recruited former US agents to spy on organizations that the right-wing considers enemies. He attacked the American Federation of Teachers, perhaps at the request of his sister, Betsy DeVos, who is Saboteur of Education. I suppose the teachers' union got in her way.

It is legitimate, and admirable, to conduct stings by making recordings of meetings in which groups propose corrupt practices. However, right-wingers don't always limit themselves to that. Prince's infiltrators rummaged around in the office files and secretly recorded the others in the office. They did not find real corruption.

They also don't limit themselves to the truth. If they don't find corruption, they may fabricate some. ACORN used to help poor people and members of disprivileged groups register to vote. Right-wingers ran a sting against ACORN. They found no real corruption, but released misleadingly edited videos that falsely suggested corruption.
