This happened a few days ago in Santa Monica....a high school teacher named Mark Black wrestled a student in self-defense (apparently over a scuffle about drug use) and is now in hot water with the school officials who called his use of physical restraint "alarming and unacceptable."

The 18-year-old student, Blair Moore, has been charged with several misdemeanors, including 2 counts of threatening a public official, 1 count of possession of a box cutter and 1 count of possession of marijuana. Yesterday, he plead not guilty.
