David Wharton (News Now Houston) has become one of my favorites at this film the police thing. He first hit the scene maybe a year or so ago, and I've watched him get better and better along the way both in his knowledge of basic Constitutional law, and how to deal with people in tense situations. A valuable life skill for any endeavor, but especially so when dealing with people who can lock you up in a cage with any missteps.
In this latest video David masterfully demonstrates the power of knowledge, making Grace Under Pressure look like child's play. It's obvious he thoroughly enjoyed this encounter, as did I, and I think you will too.

For clarity's sake, these guys don't do this for kicks. They do it as a teaching tool (for both police and the general public) that photography is not a crime, even in these days of heightened terrorism paranoia. David was arrested 3 times last year, and detained 27 times. At no point did he ever break the law...
