Why do we see black students as needing to be controlled?

In the United States, more than 110,000 students experienced corporal punishment in 2013-14. Many were African-American males. But African-American girls are also frequent victims. While 15 percent of the girls in U.S. schools are black, they account for 41 percent of the girls who experience corporal punishment, according to Natonal Women’s Law Center. Among the reasons for paddling in recent high-profile cases: dress code violations, tardiness and running in the cafeteria. The AJC found while black students comprised 37 percent of the 1.7 million Georgia students in the 2012-13 school year, they accounted for 57 percent of students expelled and 67 percent given out-of-school suspensions.
