If a police officer does something wrong. It does not matter what the evidence shows or what happens. All police everywhere stand firmly together and protect their brethren. We literally have police offers who have undeniably murdered people and yet other police still stand with their class and demand better treatment.
If workers had that level of solidarity things would be so much better. Instead we cheer when someone gets fired who “deserved” it.
It is easy to gather in solidarity when A) You are literally trained in pack tactics, backing up your fellow officer, and the culture instills an us vs them mentality by default, B) the solidarity you have is specifically in self-preservation from consequences for violent crimes that would otherwise destroy your life, and C) you are in a position of authority that gives you protection, preference, deference, and priority in all legal matters.
