Yes, in none of the cases I’ve seen has there been a clear racial component. What emerges is overzealous tactics or incompetence tipped a situation into serious harm. I think there is room for broad police reform, but we also should retain perspective.
There were just over 10,300,000 arrests in 2018, which was a low year in the USA. This breaks down to a daily number of just over 28 thousand arrests.
The number of arrests that cause death or serious harm like the OP are the rare exception, perhaps one in twenty thousand. I think I’m being generous with this since we have a handful of stories, not 500+ a year. I’m not including arrests where the person is armed and combating the police.
This equates to 5 deaths per 100k arrests. For comparison, you have twice the odds (10/100k) of committing suicide.
I think we need police reforms, which can reduce the number of these senseless deaths. However, we should to not lose our perspective. 99.995% of arrests do not end up with a headline like the OP.
