Philadelphia’s interim police commissioner has apologized for wearing a T-shirt in the 1990s that mocked the notorious Los Angeles police beating of Rodney King, saying she’s “profoundly sorry.”

The photo, from 1994, shows Christine M. Coulter, who is white, wearing a shirt that read: “L.A.P.D We Treat You Like a King,” a pointed slogan stemming from the 1991 videotaped beating of King by LAPD cops, whose acquittals sparked riots a year later.

An anonymous source sent the photo to the Philadelphia Inquirer in late August. Coulter, the first female commissioner of the 6,500-member department, said during a city council hearing Tuesday that wearing it was a “careless decision,” the Inquirer reports.

“I should have known,” Coulter said, referencing how the shirt may have been interpreted. “I am profoundly sorry that anything I would’ve done could’ve caused such hurt.”

Coulter said she wore the shirt at a gathering of cops at a hotel in Wildwood Crest, New Jersey, sometime in 1994 and insisted she “never even thought of it as anything other than an LAPD shirt,” according to the newspaper.

But one city councilwoman was unmoved by that explanation and called on Coulter to “step down immediately” in a letter she wrote to Mayor Jim Kenney, prompting cheers from the audience in the packed hearing, WCAU reports.

“I do not believe that the Acting Commissioner Christine M. Coulter can effectively manage the external relationships necessary to address police and community tensions, which is absolutely required of any commissioner,” Councilwoman Cindy Bass said in the letter.

The mayor said in a statement released later Tuesday that he didn’t think Coulter should resign, adding that a “bad decision” she made 25 years ago doesn’t negate her career of municipal service. Kenney did acknowledge, however, that the shirt was “abhorrent” and that Coulter’s decision to wear it was a mistake.

But Coulter, who became the city’s top cop after her predecessor, Richard Ross Jr., abruptly resigned last month amid allegations of sexual harassment and racial discrimination plaguing the department, has no plans to resign, a police spokesperson told The Post early Wednesday.

“Anybody that I hurt because of something that I did is something that will trouble me forever,” Coulter said Tuesday.
