A good question, thanks. This is where a 13 minute Medium read becomes 20 and nobody reads it. It's a bit of a mystery as to why.
Lightfoot was elected on the promise of police reform. When Ferguson issued reports criticizing the slowness of the city's response to specific instances of police misconduct, she went ballistic.Especially when he released the report of the police response to the protests over the George Floyd protests.
I am pretty sure that by that time she had handpicked the CPD superintendent - perhaps she was feeling defensive?
Ferguson's attempt to push police reform seemed to be at the center of their problems, but the why of that remains a mystery, since she was elected on that promise.
