I think people should always obey police. They have a hard job.

It's true, police have a very difficult job. I wouldn't want it. And there are some people who are very good at it.

It's tough being a musician, too. But that's no excuse for dropping notes in a concert. People don't go to a concert and walk out saying "wow, that was really bad, but really it's hard being a musician, so it's ok that the soloist forgot where he was and dropped a bunch of notes and made the orchestra start over."

Policing is a profession and we can expect professional behavior. Can't we?

If they break their own rules, or seem to be going over the edge...

What would you do if you were walking peacefully down the sidewalk and a cop came over to you, yelled at you and said to get down on your knees?

I honestly don't know what I'd do.
