If it wakes people up, great. I don't have a problem with what Project Veritas does, for example. How else do you infiltrate and expose? You can't walk up to them and say, "I'm a pro-lifer. You know, your enemy. Please give me a tour of your abortion facility."
Oh, Project Veritas is absolutely justified in doing what it does. In this case, though, I don't think this woman is evil, just a dummy, and I kind of feel for her being embarrased like that.
