That's not even what entrapment is, either. Entrapment is coercing someone into committing a crime that they otherwise wouldn't have. For example, blackmail is entrapment if you use the threat of exposure to get them to commit other crimes.

In my experience, people who think that secretly recording someone doing something bad is "entrapment" tend to be teenagers with a very tenuous grasp of how the world works, or mentally ill adults. Not a coincidence that both of those groups dominate Wikipedia.
