You only need to watch the first 30 seconds or so, the rest is unnecessary. At the end, a bank employee escorts the photographer out.

The cop just completely makes up the line about having to be informed of recording as the court case cited in the video points out. But such behavior has been documented on this website dozens of times. Cops routinely lie or are misinformed of the law.

But, I bet 99% of the time when that cop just makes something up, people do what he says, so he has little incentive to actually know the law–he thinks he is the law. He has a gun, and if you reject Christianity, the only foundation of law is: Might makes right.
