A investigation has began after a retired detective was captured on camera using a racial slur during a confrontation during a encounter with a Black man according to The Los Angeles Police Department. A video posted to social media was reportedly taken last Saturday following a crash in Valencia, California as shows the former detective, identified by police as John Motto. Motto demands the other man provide his driver’s license and yelling a racial slur at the man.

“For any of you that have seen this video, it’s horrific,” L.A. County District Attorney George Gascón said. “It really illustrates, you know, incredibly racist attitudes by this individual.”

Last Tuesday, Gascón announced that his office would review 370 old cases where the detective was reportedly a witness.

“Under the law, we are required, once we are aware of someone having racist tendencies, as in the case of the individual, we have to notify all the defense lawyers in all the cases that this individual may have been a witness or participated in the investigation,” Gascón said. LAPD said Motto retired from the Operations Central Bureau Homicide in May 2020 and the department had launched its own investigation.

LAPD says Motto was not subject to disciplinary action as a former employee, however, said the department was working with the D.A.’s office to review the cases.

“They’re going to question whether or not evidence was planted,” civil rights attorney DeWitt Lacey said. “They’re gonna question whether or not he ignored evidence from people of color, Black folks in particular. They’re gonna question the type of people he went after.”

The D.A.’s office said it would begin its review with pending cases and work its way backward. CBS Los Angeles attempted to reach out to Motto, but did not immediately hear back.
