If it's true that Professor Henry Louis Gates of Harvard was already inside his home, having proven residency before the officer arrested him, then I think the officer WAS indeed stupid,
and yes, "profiling" (racism) seems to have occurred. This policeman's colleagues didn't distinguish themselves, either; they appeared to be shocked that they could ever be accused of less than stellar behavior. So here's a news flash for them and everybody else: everyone commits acts of stupidity before they die, a bitter, inevitable fact of life. The president was right to defend his friend; I would have recognized Prof. Gates, but then, I've seen him often on PBS.
Mr. Obama, don't bother setting up a future "kumbaya" meeting with this cop, you have far more important issues to attend to--the economy, health care, Afghanistan, foreign relations, etc. You really don't have the time, and shouldn't have the focus.....please move on. Let Prof. Gates, a very capable individual, handle this; he may choose to file for harassment, or take other action.
Meanwhile, the rest of us need you.
