How many Harvard profs do you think live in that neighborhood? My guess is they are neighbors and probably pretty diverse, sort of like Hyde Park in this locale. I guess you think it a better idea not to call the police when one observes something like shoulder being put to a door? In this case it definitely would have been fine NOT to have called it in, but let's give the woman the benefit of the doubt and she didn't recognize the professor and there were 2 men trying to get in. If it were your home, would you want your neighbors to play Kitty Genovese scenario for you?
You have to wonder though, how many burglars break into the front door with luggage at their feet?
Regardless, if the police received a 911 call your house was being broken into, wouldn't you want them to investigate? And wouldn't you want them to insist on confirming, regardless of appearances, that the person they found there did have a right to be there?
Gates was not calling the person who made the 911 call a racist; he was calling the cop, who was doing exactly what you or I would want him to do, a racist. Regardless of what Gates and Obama may believe about American history, nothing in the cop's behavior justified calling him a racist - if Gates is unable to evaluate the cop's behavior on its own merits because the cop is white, then Gates is the racist - and demanding special treatment because of his status at Harvard or because of his presumed influence with the mayor or police chief should have been unacceptable to anyone who believed in equal rights under the law. To the extent Obama's prattle about racial profiling in the US was intended to justify Gates' outrageous behavior, he has revealed himself to be a racist, too.
