Here is a statistic from an article by John Lott.

Others, like the American Bar Association, claim racial biases in how the death penalty is applied. In fact, while African-Americans have committed 53 percent of all murders since 1980 in which the killer's race is known, they have accounted for only 38 percent of the executions.

A few years ago the Ft. Worth Star Telegram printed photos of all people executed in Texas the previous year. It was obvious that a lot more of those executed were white. For some reason liberals concentrate on the number of blacks executed compared to the percentage of the population that is black. Black men are more than 8 times more likely to commit murder than white men. So, given that about one-eights of the population is black, it would be expected that about the same number of blacks as whites would be executed.

By the way, there were no women executed that year. Women are over half of the population, but are rarely executed. Do liberals wonder why that is? The answer, of course, is that very few women commit murder.
