“I want to take about 20 seconds to apologize for all the things that the police have done dating back 200 years,” Commissioner Darryl De Sousa said at Wednesday’s Eric B. & Rakim concert at Baltimore Soundstage.

A video posted by Baltimore Fishbowl shows De Sousa being met with a few applause but mostly boo’s — as well as several profanities.

“Two hundred years ago, all the way to civil rights. All the way to the ’80s where crack was prevalent in the cities and it affected disproportionately African-American men. All the way to the ’90s. All the way to the 2000’s when we had zero tolerance,” De Sousa added.
