Reverend Preston Thompson, chief pastor of Ebenezer Baptist Church in Englewood, said the police had forgotten that their job was « to protect and serve. »

« The entire system is isolated to protect its own system, » said Mr. Thompson. We have to fight it. They will not do self-policing and so we people have to make sure that we come and protect ourselves.  »

Mayor Wildes, a former federal prosecutor who participated in more than a dozen rallies at the Black Lives Matter rally in Englewood, said he believes every one of the 72 police officers is committed to serving the public.

He said, « There is not a single officer who cannot survive in the face of danger to save someone, or to help a resident. »

He added, « But for me, making sure the city’s leadership for this division is really improving is the mission of 2021. »
