Your plan is a very smart way of approaching the situation properly. Obviously Castile did not know this or chose not to follow this when he was shot. I'm sure you would agree that this does not make him a "criminal resisting police capture" but rather a man who made a mistake or a very bad choice.
Yes, I agree, this was a very unfortunate misunderstanding that resulted in the death of Mr Castile.
believe the bigger issue here that the protestors are trying to bring to the forefront is that police enter an interaction with a black man with a heightened sense of danger...which is far more likely to end in tragedy.
If a white man in a business suit driving a Mercedes was in the same exact situation as the above, and did the exact same thing, the officer possibly would have told the man: "bring the gun out slowly with your finger off the trigger and place it on the dash". Maybe not...I don't know.
Police enter an interaction with a black man with a heightened sense of danger...because it is more dangerous.
This didn't happen in a vacuum...these officers are conditioned by the interactions they experience everyday. When police interact with white businessmen in suits, and 999 times out of 1,000 police have an uneventful encounter, that builds a conditioned response. Conversely, when police interact with black drivers in cars that reek of Marijuana, what type of encounter do you expect that interaction results in regularly?
When 52% of homicides nationwide and 38.5% of all violent crimes are committed by 7% of the population, black males, that statistically makes the interactions with black males absolutely more dangerous.
In my opinion, the protest is for a good reason...to increase awareness, to make people think before acting. It would be nice if the protest turned into action to force politicians to admit there is a problem, to increase/improve training of LEOs on how to diffuse situations, and to encourage and teach civilians (especially young black men and boys) on how to safely and respectfully deal with authority.
The problem is multifactorial and both sides have a role to play. However, one side has guns and power, while the other side is economically disadvantaged and has historically been oppressed.
I understand your point, and it is an admirable position. But what you are asking is for police to act in way contrary to their own experience. Their own self preservation instinct are never going to allow this. Nothing is going to change until the black community changes. Police won't stop responding to encounters with black citizens with a heighten sense of danger until such a time as the actual probability of a dangerous interaction is reduced.
