This guy definitely knows his rights!
From the YouTube description
I was detained by Portland PD officer J McDonald on 26MAY2012. He detains me without suspicion of any criminal activity in violation of Delaware v Prouse. He admits his sole reason for stopping me is my legally carried firearm in violation of US v DeBerry. He seizes my weapon with no reasonable suspicion that I’ve committed a crime in violation of Terry v Ohio. He demands my ID without reasonable suspicion in violation of Hiibel v Nevada.
