They count, and it is why the statement is idiotic.
And it is idiotic in more than one way.
First, the number of blacks who are criminals is nowhere near 50%, for any age group. That is simply absurd.
as an example, from an older version of the crime statistics, the rate for 18-under blacks was 2.8%, and the rate for over 18-blacks was 3%.
Second, a large number of blacks who are criminals are actually in prison, so the chance of you running into one of THOSE blacks is low, except as I said if you are in prison. The criminal rate for blacks who are NOT in prison is much lower.
It is stupid statements like yours that cause real trouble. The idea that any black you run into has a 50-50 chance of being a criminal is exactly the kind of assinine “profiling” that makes it hard for those of us who want to profile appropriately.
In Atlanta, blacks are 54 percent of the population, but are responsible for:
100 percent of homicide
95 percent of rape
94 percent of robbery
84 percent of aggravated assault
93 percent of burglary.
