Cops are no better or worse than anyone else.
Don't move the goalposts now! I never said cops were "better" than anyone else. My main point is that their mental health is monitored more than most people because of the nature of their work. Of course it is well known that there are bad cops - beating up someone they're arresting, taking bribes, etc., but those things are a bit of a leap when you think of a cop at a shopping mall or a school or an airport.
