It should be like that. If the mayor won’t support the police, why should they risk their lives...
All the mayor did was say that there would be a review of the police department, and that was following the department's shooting an innocent paramedic during a no-knock warrant on the wrong address looking for someone they had in custody to begin with and the shooting of a unarmed restaurant owner during a protest. What exactly should the mayor have done? Support shooting innocent people? Vocally support no-knock warrants on the wrong address? Say that the unarmed demonstrator had it coming to him? Maybe if the police department hadn't screwed up so tragically and so incompetently in the last few weeks he wouldn't have had to say anything.
