Some government-supremacists who aren't terribly situationally aware argue that a cop wouldn't intentionally commit murder in front of witnesses and cameras.
How does this belief measure up?
Would cops murder someone while they know they are being watched and recorded?
Well, sure, if they believe they are immune from real consequences. In other words, if it's an average legislation enforcement officer who is aware of how this usually plays out for murderous cops committing the murder.
Cops aren't afraid to murder because they usually get away with it, no matter how blatant it is. Even if "charged" with a crime. Juries are stacked with copsuckers. Prosecutors belong to the same gang as the cops. As do judges. A murderous cop has to be really careless to suffer real consequences.
There are many dumb, pointless ways to "reform" the police. There's also one good way to solve the problem.
Abolish the police.
