It took less than a day for the arrest of Henry Louis Gates to become racial lore. When one of America’s most prominent black intellectuals winds up in handcuffs, it’s not just another episode of profiling — it’s a signpost on the nation’s bumpy road to equality.

The news was parsed and Tweeted, rued and debated. This was, after all Henry “Skip” Gates: Summa cum laude and Phi Beta Kappa graduate of Yale. MacArthur “genius grant” recipient. Acclaimed historian, Harvard professor and PBS documentarian. One of Time magazine’s “25 Most Influential Americans” in 1997. Holder of 50 honorary degrees.

If this man can be taken away by police officers from the porch of his own home, what does it say about the treatment that average blacks can expect in 2009?

Earl Graves Jr., CEO of the company that publishes Black Enterprise magazine, was once stopped by police during his train commute to work, dressed in a suit and tie.

“My case took place back in 1995, and here we are 14 years later dealing with the same madness,” he said Tuesday. “Barack Obama being the president has meant absolutely nothing to white law enforcement officers. Zero. So I have zero confidence that (Gates’ case) will lead to any change whatsoever.”

The 58-year-old professor had returned from a trip to China last Thursday afternoon and found the front door of his Cambridge, Mass., home stuck shut. Gates entered the back door, forced open the front door with help from a car service driver, and was on the phone with the Harvard leasing company when a white police sergeant arrived.

Gates and the sergeant gave differing accounts of what happened next. But for many people, that doesn’t matter.

They don’t care that Gates was charged not with breaking and entering, but with disorderly conduct after repeatedly demanding the sergeant’s name and badge number. It doesn’t matter whether Gates was yelling, or accused Sgt. James Crowley of being racist, or that all charges were dropped Tuesday.

All they see is pure, naked racial profiling.

“Under any account … all of it is totally uncalled for,” said Graves.

“It never would have happened — imagine a white professor, a distinguished white professor at Harvard, walking around with a cane, going into his own house, being harassed or stopped by the police. It would never happen.”

Racial profiling became a national issue in the 1990s, when highway police on major drug delivery routes were accused of stopping drivers simply for being black. Lawsuits were filed, studies were commissioned, data was analyzed. “It is wrong, and we will end it in America,” President George W. Bush said in 2001.

Yet for every study that concluded police disproportionately stop, search and arrest minorities, another expert came to a different conclusion. “That’s always going to be the case,” Greg Ridgeway, who has a Ph.D in statistics and studies racial profiling for the RAND research group, said on Monday. “You’re never going to be able to (statistically) prove racial profiling. … There’s always a plausible explanation.”

Federal legislation to ban racial profiling has languished since being introduced in 2007 by a dozen Democratic senators, including then-Sen. Barack Obama.

Amid the indignation over Gates’ case, a few people pointed out that he may have violated the cardinal rule of avoiding arrest: Do not antagonize the cops.

The police report said that Gates yelled at the officer, refused to calm down and behaved in a “tumultuous” manner. Gates said he simply asked for the officer’s identification, followed him into his porch when the information was not forthcoming, and was arrested for no reason. But something about being asked to prove that you live in your own home clearly struck a nerve — both for Gates and his defenders.
