@Diest TKO,
Being asked to step outside may have been standard police procedure - no one has confirmed or repudiated this assertion, and, in any case, it's not being treated like a criminal.
Being asked for ID is not being treated like a criminal.
Being arrested is being treated like a criminal, and at the time the arresting officer believed Mr. Gates to be guilty of a crime.
The fact that Gates was in or around his house is immaterial to whether or not he committed a crime. Your house is not some legal sactuary where anything you do cannot be considered criminal.
Whether his indignation was righteous or overblown, Gates made a scene and acted like jerk. A neighbor reports that two black men may be breaking into a house and the police investigate and have the temerity to ask him for ID. The fact that black men have been unfairly persecuted by police in the past, doesn't mean that every interraction between a cop and a black man involves profiling or racisim. I don't blame the guy for being annoyed, frustrated or angry, but his actions weren't justified. They may not have been criminal, but they weren't justified.
I don't think Crowley should have arrested him simply because he was acting like a jerk. He should have just left the scene and saved the story for the locker-room or dinner at home. It
was stupid of him to put himself in a position where he had to arrest Gates: Giving him repreat warnings that he would arrest him if he kept up his jerky behavior. The police are supposed to be able to handle these situations without taking the jerky behavior of a suspect or a citizen personally.
It would appear that Prof. Gates is still acting like a jerk, and lying about what transpired to boot.
I don't have a huge problem with the way Obama answered the question last night, but then I don't think of him as being perfect. I'm sure he was incredibly thankful to get a question that didn't have to do with healthcare.
