You're the second person here to make this insanely tone-deaf comparison. People don't choose to be black. The fact that people here are so quick to make this comparison is scary.
They choose to be cops so they can protect and serve the community and put their life on the line every day.
They don't choose to become cops so they can kill black people for no reason whatsoever - that's the only "scary" and dangerous belief here. They're not "getting away with murder" in most of these high profile cases. I bet Kaepernick thinks Michael Brown was innocent and the cop is one of those who he thinks got away with murder. That's the incident that really kickstarted this Black Lives Matter movement.
They choose to be cops. Police have earned a bad reputation by committing heinous crimes, getting caught, and still not facing consequences. Generalizing like with the socks is a bit much, but it's valid for a black person to fear and antagonize police whereas it's not valid for some random person to depict black people as apes.
So with this logic... if a black person chooses to be a criminal,
then they be depicted as an ape? Valid?
Cops are killed by blacks at a higher rate than cops kill blacks, by the way. You wanna talk about bad reputations, heinous crimes and make generalizations... look at the statistics and disproportionality.
Also, in the few cases per year where a black person is killed by a cop for absurd, unequivocally unjustified reasons (just as white and Hispanics are too) - it's a matter of the cop being incompetent as hell/overreacting/trigger happy idiot in the heat of the moment. They often do go to jail, too.
(see: Walter Scott/Michael Sleger, Alabama cop, South Carolina gas station cop.. Those are just off the top of my head)
To make the baseless assumption that it's because the cop(s) in each incident are racist - is absurd. If a cop truly wanted to kill a black kid as a result of racism, he wouldn't do it in a public park, gas station, etc. with a high likelihood of people around.
