I assume that most people in prison will be non-white, because that is what history has shown me to be true. I beleive it will be true tomorrow. That is an assumption, based on evidence, and it is no more racist than the previous assumptions. It is an educated and reasonable supposition.
It is not a certainty. When it is foolish to consider the alternative, it is reasonable to presume.
It is not racist to presume that a violent criminal is black in a vacuum of facts. The only fact we have is that, statistically, it's most likely a black guy. That statistic is a fact, and it's the only one we've got. It would be stupid to presume that the crime was commited by an alien from another planet. Statistics are all we have to go on here, and those numbers cannot be lied about. Math is not racist. Nor is basing one's decisions, beliefs, etc., upon it.
Science is not racism.
One shouldn't assume. A quick check shows that most people in prison are white. Which makes sense as the majority of people in the US are white. about 13% black and 13% Hispanic, a few Asians, etc.
