Police need to know how to treat crime victims on the scene.
Shortly after the July police shooting that occurred in Dallas, in which five officers were killed and nine others were injured, Dallas Police Chief David Brown publicly lamented that the public was "asking cops to do too much in this country."
"Every societal failure, we put it off on the cops to solve," he said during a press conference after the event, according to the Washington Post. "Not enough mental health funding, let the cops handle it. … Here in Dallas we got a loose dog problem; let's have the cops chase loose dogs. Schools fail, let's give it to the cops. … That's too much to ask. Policing was never meant to solve all those problems."
