The following can be attributed to Karen Sheley, Director of the Police Practices Project at the ACLU of Illinois:

It is disconcerting – once again – to see how little President Donald Trump comprehends about policing in Chicago. He offers an “immediate” solution to gun violence – aggressive policing. We know what he means – this summer he told a room of graduating police officers to physically abuse suspects. Trump’s Administration shirked its responsibility to address excessive force in Chicago after a damning report by President Obama's Department of Justice. Now he calls for more abuse. 

Because of the Trump Administration’s unwillingness to do the necessary work to restore trust between the police and the communities they serve, the ACLU has just gone to federal court on behalf of several community groups who are seeking real reform. Chicago should listen to them, not Trump's invocation of a mystery, unnamed police officer, used only to encourage more police violence.
