Since the subject of school discipline was raised in this wide ranging thread, I'd like to post a link to an article on that subject, and share portions of that article.

School discipline tougher on African Americans
By Howard Witt | Tribune senior correspondent
September 25, 2007

..."In every state but Idaho, a Tribune analysis of the data shows, black students are being suspended in numbers greater than would be expected from their proportion of the student population. In 21 states—Illinois among them—that disproportionality is so pronounced that the percentage of black suspensions is more than double their percentage of the student body. And on average across the nation, black students are suspended and expelled at nearly three times the rate of white students.

No other ethnic group is disciplined at such a high rate, the federal data show. Hispanic students are suspended and expelled in almost direct proportion to their populations, while white and Asian students are disciplined far less.

Yet black students are no more likely to misbehave than other students from the same social and economic environments, research studies have found. Some impoverished black children grow up in troubled neighborhoods and come from broken families, leaving them less equipped to conform to behavioral expectations in school. While such socioeconomic factors contribute to the disproportionate discipline rates, researchers say that poverty alone cannot explain the disparities. "There simply isn't any support for the notion that, given the same set of circumstances, African-American kids act out to a greater degree than other kids," said Russell Skiba, a professor of educational psychology at Indiana University whose research focuses on race and discipline issues in public schools. "In fact, the data indicate that African-American students are punished more severely for the same offense, so clearly something else is going on. We can call it structural inequity or we can call it institutional racism."
