-> The social scientist's view of who commits crimes is a set of snapshots—the report of a crime, an arrest, the decision to prosecute, the charge on which the suspect is tried, the outcome of the prosecution, and the sentence for a guilty plea or verdict. At each step, the authorities are usually trying to get it right, but "getting it right" means different things. Decisions to prosecute depend on many factors besides the likelihood that the arrested person committed the crime (e.g., whether these is evidence to prove guilt beyond reasonable doubt if it goes to trial). The decision about the charges that will be filed is a main bargaining chip in a plea bargain negotiation.

-This is all very "reasonable" by the methods and epistemology of Murray's world, and I'm afraid—not a figure of speech, actually afraid—that there's nothing I could say, no words I could possibly type to explain the cruel and capricious insanity of that world's "reasonableness" to those who haven't personally been on the other side, who have never been abused by a total institution like the "justice" system.

+Perhaps you could argue both that the tests are racist and that teachers are _even more_ racist?—but you'd want to be specific about what alternative metric of "merit" you think they're being racist _with respect to_. The thing about tests is, a vast space of "objective" procedures can come up with a number, without giving anyone a reason to care about that particular number; if you care about group rank orderings, you _could_ come up with a measurement that gets the the group rank ordering you want. (Black people have more melanin than white people, on average! People with more letters in their name take longer to say their name out loud, on average! Cats do better than humans on a test of scratching, on average! "Hispanic" comes before "White" in alphabetical order!) The problem is that it looks like the "cognitive ability" thing that psychometricians are trying to measure is actually a pretty robust abstraction that summarizes variation _in individuals_ that people care about (like the ability to master a profession); if it were just a tool of racial oppression, it's hard to see why it would work so well _within_ groups.
