Anecdotes have little value.

Anecdotes by someone trying to sell a book with a contrarian spin have less than no value.

Black Americans are significantly more likely to be stopped than White ones and the consequences of that stop are far more likely to be fatal.

My anecdote is that I lived in America as a white guy with an English accent for thirty years, mostly in Democrat-majority states, and I heard Americans express some of the most vile racist shit you can imagine, because they thought I was a natural ally.

Oh, and I got stopped by cops zero times.

But the actual peer reviewed numbers are the important part.
