“...was shot five times while cooperating with an officer’s instructions.”
Have you heard the recording from the police car?
If so, then you KNOW that the above statement is wildly inaccurate.
If you haven’t heard the recording you need to - quickly, in order to remedy your ignorance.
It was not Castile’s fault that the nervous, poorly-trained cop gave him two conflicting instructions.
In both cases the police officer used deadly force in a situation that did not call for it. In both cases a person is dead who should not be dead, killed by a police officer who probably should never have been a police officer. In the Castile case the police officer got of by claiming he feared for his life. I expect the police officer in the Diamond case will use the same defense with the same results.
