Without stooping to the tone that you have ("you must have flunked civics") I am going to respond to you in a civilized manner:
Re read post 51. He explained to you once already the officers justification.
His Constitutional rights were violated by the 1 1/2 hour "detention" (really an illegal arrest) to which he was subjected.
Lets back up a second: Why was he 'detained' for an hour and a half?
Answer: because he refused to identify himself or to answer simple and reasonable questions. By his lack of cooperation, he was wasting the time of eight cops (or was it ten?).
If he had said: Hey guys, whats up? me? Oh, I am just a reporter fishing for a story, here is my Post ID. You guys were quick, by the way.
He would have been gone in five minutes and possibly even have had a better story!
Yes, but those people don't believe any question from a police officer (or to use their term "jack-booted thug") is simple or reasonable.
