What about Charles Kinsey, a therapist trying to calm an autistic patient?!!!   He immediately complied, lay on his back with his hands straight up in the air, and a cop shot him!   They approached with guns out and screaming at him to 'get down' as soon as they saw him!  

What about Sandra Bland, and how she was treated?

What about the bikini-clad 14-year-old thrown on the ground by a cop, who then knelt on top of her while waving a gun at other youngsters?  They had gotten too rowdy for a neighbor, and that's how the complaint was investigated.

I have never had a police officer treat me with anything but professional courtesy, and nine out of ten po-po that I have had contact with for any reason have been great and given me breaks on lapsed registration and other minor transgressions.   But I am also aware of the long history of racism in the US toward people of color, and it has shaped the country.
