Statistically speaking, there are 6x more white people in American than there are black people.
So, what your statistics show is that, instead of 6x more white people being shot by police in 2017 and 2018, there are only 2x more. Or, a third of what the number would be if white were shot by police at the same rates as blacks.
The numbers indicate that blacks are shot by police at a far higher rate, based upon their representative fraction of Americans, by race.
Simpler: The black population in America is 1/6th the white population, and as such, SHOULD statistically have 1/6th the number shot by police. Instead, their rate is 3x higher (1/2 the number). That's a problem.
Maybe I trust our law enforcement too much, but I will stick with the old don't be a criminal and you have a near 0% chance of dealing with law enforcement. We could get into where white folks live vs. where black folks live (as a whole, in general) but I have work to do and I know I am not going to change your mind.
