As a little anecdote, I can count the number of black men I've ever had at gunpoint on my fingers.
I dont think I could count the number of white men Ive had at gunpoint per year on my fingers and toes.
That makes sense when you realize Washington State is 71.6% white and only 3.6% black. Based on proportions of the population in Washington you are far more likely to interact with white suspects than black suspects, even if blacks commit crimes at rates disproportionate to their percentage of the population.
