Much of the commentary, even from conservatives, about William Bennett's alleged faux pas misses the mark. Ed Morissey at Captain's Quarters is an example:
This is all beside the point. The reason why Bennett used the construction "black baby" is clear to anyone who understands the context of the remark. He was commenting on a study that appears in a book called Freakonomics in which the authors show a correlation between the onset of large-scale abortion on demand in this country in 1973 and lower crime rates beginning about 18 to 20 years later. The authors, Steven Levitt and Stephen Dubner, argue that the correlation exists because crime is largely a poor minority phenomenon and so is abortion.
In other words, the authors argue that because there have been millions fewer black babies born in the last thirty years, crime has gone down (Their thesis may be right or wrong. It's a mistake, however, to think that they were advocating abortion as a means of reducing crime, much less abortion of black babies. They were simply noting a correlation).
Bennett was nevertheless objecting to the notion that abortion should be seen as a legitimate means of reducing crime rates. With the Levitt/Dubner book in mind, he was in effect insisting that aborting babies, even those in the high-crime demographic, even if crime could be profoundly curtailed by so doing, is a reprehensible social policy.
That's all Bennett was saying. Whatever it might be that's wrong with what he said we confess that it eludes us.
