Wait a minute. WHY WOULD WE BE ANGRY? WE'RE THE HOME OWNER. Someone was worried about our house and called it in. The cops are there to protect my house. Why should they know who I am? Why shouldn't they be worried about the possibility that while they were on their way over someone broke into my house and is still there?

Cops go into unknown situations and have to pick up on a host of facts and details that may not all be apparent.

The varied attitudes and assumptions that people bring to this thread only emphasize what a mixed bag this whole incident is. If you've got blinders on you're going to concentrate on one aspect or another, but what was going down was several things:

Report of an apparent crime, partial description of the suspects.

Class division- Harvard don and city cop.

Racial division- Black homeowner, white cop, (white witness?), potential home breaker reported as black

cop attitude not to back down at a challenge

this is more than enough to create a problem out of nothing, which is exactly what happened.
