Any cop that would quit for moral reasons is the type of cop who probably shouldn’t. This message only makes things worse.
One of the best officers I knew quit after being called to a protest over the killing of a black man. He had to stand in front of people who he may have agreed with and take physical and verbal abuse. The last thing he told me was “In insurance they don’t throw bottles at your head for doing your job.”
I still know a lot of good people in law enforcement, but things like that sure do make it difficult to encourage good people to stick around.
