Thank you for the article.
If it convinces some people that African Americans do not commit more crimes (proportionally) than other ethnicities, that is fine.
But most people will not accept that argument. They know from personal experience (or what they have read) that -- for example -- almost all of the people that commit crimes on the New York subway, for example, are, well, you know the answer.
Even the Rev. Jesse Jackson many years ago admitted that he would be, uh, concerned if he walked down the street at night and realized that he was being followed by, well, you know the answer.
Have a nice day!
