“His conduct is unbecoming, filled with ethical lapses and flawed decision-making,” he said.
Franklyn Gimbel, a lawyer for Mr. Morales, said the former chief was considering his options and would “cooperate with the acting chief to serve the people of Milwaukee in the interim.”
Michael Brunson, who had been the assistant chief, will become the acting chief. In a statement on Thursday night, Mr. Brunson said he had “great respect for all of the men and women of the Milwaukee Police Department,” and thanked Mr. Morales for his service.
“I look forward to continuing to serve the residents of this city,” he said.
Like many other police departments in the United States, Milwaukee’s has been challenged by protests stemming from the death of George Floyd, as longstanding grievances have bubbled over into broader calls for police accountability. This week, Mr. Morales defended the department’s use of tear gas to break up protests on six occasions, saying that each use was needed to disperse crowds that threatened violence, according to The Milwaukee Journal-Sentinel.
The 11 directives called for further explanation of several high-profile cases, including an officer’s use of a stun gun against Sterling Brown, an N.B.A. player, in May 2018. Mr. Morales said officers in that case had acted inappropriately; eight officers were disciplined but not fired.
The directives also included demands for a policy requiring officers to wear masks during the coronavirus pandemic and for a partnership with local organizations to create community policing standards.
