Anyone can be affected by this, which is why police brutality should be an everyone issue, but statistically speaking you are correct.

(There are many other, more dangerous places in the world where you shouldn't call cops for things like this, but probably everyone there knows why, so you don't have to caution the statistically unlikely subset not to do this.)

It's a warning for everyone. Caucasians have plenty of bad interactions with police, especially surrounding mental health. Also, depression is increasing fastest in white men.
