Because I’m not offering the personal experience of how I’ve been treated by the police. That’s what I’m objecting to. If you want to argue with me about how blacks are treated by police with statistics and other facts and studies, well and good. But neither you nor I can offer personal stories of our own interaction with police- they’re just not relevant.
Years ago I was at a picnic with a black family at Echo Park in Los Angeles. A friend of mine from my chess playing days was introducing me to his wife and kids. The police showed up and, in front of the guys family and me, handcuffed my friend and dragged him away. They had gotten a report of a robbery in the area. My friend was humiliated and had to be questioned at the police station for hours, before the cops found the right guy.
I will never know what my friend must have felt. That was an experience that would NEVER happen to me, or any white person. It helped me to partially understand what black people go through on a daily basis, but I can never fully understand. All I can do is try to help end such treatment, and that starts by helping other white people to partially understand as well. If that seems patronizing to you I apologize.
