I can't watch the video so i can't critique as critically as i want but let me lend a word of advice to everyone.
just because you have the right, doesn't mean excercizing it is the best thing to do. Sometimes the mere use of your rights can either give them "reasonable suspicion" to violate your rights, or just plain piss the cop off. The last thing you want is to piss a cop off. Let them feel you're not doin' anything harmful and you're basically showing them everything there is to see. If you do this, they feel respected and don't want to prod much further, otherwise you're about to get ass rammed by a nazi.
i speak from experience. here is the story:
Summer in high school, a month before Senior Year starts: After i drink 6 beers at a party people decide we need more beer, so my friend james, will, and i go out to steal more beer (we already stole a keg for the party). We go to an am/pm but i'm too drunk to help and jump the fence to get the beer, so i stumble inside for a piss and a candy bar. I come out to a scene of police lights. I had legal training from a protest the week before, so i start walking away when two security gaurds come up to me and says, "this cop wants you to come talk to her" and i say "am i being detained?" They looked perplexed so i explain to them, "i'm not required to be in the presense of a police officer if i'm not being detained, so if i'm not, i'm leaving." Then i leave. Then they come back and get me once getting authority to detain me. I refused to give the cops my name or anything about the story. the other two accomplices i'm with spill their guts about EVERYTHING including the party location and the plan to steal. Even though they were the ones doing everything, they go home within an hour of arriving at the police station. I, on the other hand, the one who used my rigths every step of the way, didn't get to phone my parents for 5 HOURS as i lay hand cuffed to a bench and poked out with night sticks when i attempt to pass out. The entire 5 hours they're telling me i'm going to Juvenile Hall, they're just going through the paper work. I'm in the main room mind you, where all the cops with nothing to do can come in and just rip on me. finally at 5am they say they're just not going to take the time to go through the paper work.
i learned my lesson. Be careful with your rights, you don't really have any.
