(CNN) Former New York City Mayor Michael Bloomberg made it official Sunday, announcing that he is seeking the 2020 Democratic nomination for President. And, as would be expected, Bloomberg's first campaign commercial -- part of his $37 million ad buy -- touts his record as a three-term mayor of the Big Apple. In it, he boasts that he "took charge of a city still reeling from 9/11," adding that he "helped bring it back from the ashes." He also brags about his record of job growth and more.

I lived in New York City during the Bloomberg administration, and I can tell you first-hand he was a great mayor for some -- but not for those who were black, brown or Muslim. Bluntly, Bloomberg's policies sent a message that blacks, Hispanics and Muslims didn't deserve the same civil rights as other New Yorkers enjoyed.

Bloomberg's "stop and frisk" policy was as racist as it gets in terms of its real-world impact . As the ACLU documented, during Bloomberg's 12-year tenure as mayor, there were more than 5 million "stop and frisk" stops. "Though they accounted for only 4.7% of the city's population, black and Latino males between the ages of 14 and 24 accounted for 41% of stops between 2003 and 2013," the ACLU wrote. The report also made it clear that the policy overwhelmingly targeted people who had done nothing wrong: "Nearly 90% of young black and Latino men stopped were innocent."

In fact, in 2013, a federal judge ruled that Bloomberg's "stop and frisk" policy was unconstitutional because it violated the Fourth Amendment's protections against unreasonable searches and seizures and the 14th Amendment's guarantee that all Americans are to be treated equally regardless of race.
