You could not ask for a more perfect illustration of the thesis of my latest book, "Guilty: Liberal Victims and Their Assault on America," than the black president of the United States attacking a powerless white cop for arresting a black Harvard professor -- in a city with a black mayor and a state with a black governor -- as the professor vacations in Martha's Vineyard.

In modern America, the alleged "victim" is always really the aggressor, and the alleged "aggressor" is always the true victim.

President Barack Obama planted the question during a health care press conference, hoping he could satisfy the Chicago Sun-Times, which has been accusing him of not being black enough. He somehow imagined that the rest of the country might not notice the president of the United States gratuitously attacking a cop in a case of alleged "racial profiling."

Oops.

Suddenly, with the glare of the national spotlight being turned on a small local story, it became clear that there was no "racial profiling" involved -- other than by the black Harvard professor, who lorded his credentials and connections over a white working-class cop.

We wouldn't have known about this case at all if the professor, Henry Louis Gates Jr., hadn't blast e-mailed the universe that he was harassed by racist cops. Gates thought it would be a feather in his cap, not realizing there are huge areas of the country where people don't think it's heroic to browbeat cops checking on you after you break into your own house, such as 99 percent of the country outside of Cambridge.

Contrary to liberals' ardent desire, Sgt. James Crowley was not on tape saying, "I know it's his house, but let's stick it to this uppity negro." (Curiously, the tape of Gates' call demanding to talk to the chief of police to "report" Crowley has been withheld. Some watchdog group has got to demand that tape.)

But what if Crowley hadn't been a model policeman who taught diversity classes and once famously gave mouth-to-mouth resuscitation to a black athlete?

What if the 911 caller had identified the suspected burglars as black, which it turns out she did not?

What if Crowley hadn't been fully supported by other cops at the scene, one Hispanic and one black? (Liberals will say cops stick together, but I say liberals stick together.)

What if, at some point in his life, Crowley had been accused -- falsely or not -- of racism?

His life would be ruined.

Desperate to blame the cop, despite the facts, some liberals have begun making up their own facts. Radio talker Opio Sokoni claimed Crowley told Gates to "shut up" and "I'm going to win, you're going to jail." Even Gates doesn't claim the cop said that.

On MSNBC's "Hardball," Chris Matthews said that Gates did not say, "I'll speak with your mama outside," as stated in the police report.

"He didn't say this," Matthews asserted as fact. This invented fact allowed Matthews to accuse the cop of engaging in "projection" and to conjure Crowley's psychological state, saying, this is "what a white guy thought a black guy would say."

Eugene Robinson endorsed Matthews' invented fact, saying: "I cannot imagine in this universe Skip Gates saying, 'I'll speak with your mama outside.'" As proof, Robinson explained that Gates "rolls with kings and queens and Nobel Prize winners." (I'm not "projecting" what I think a black man would say; he really said that.)

And then they both had a laugh about the cop applying racist stereotypes to such an esteemed figure as Professor Gates, who apparently would NEVER use the phrase "your mama." Continued...
