Seminole State College has expelled George Zimmerman, the man who shot and killed Trayvon Martin, setting off a debate over whether Florida has been too slow to charge Zimmerman in the shooting, WKMG News reported. College officials released a statement saying: "Due to the highly charged and high-profile controversy involving this student, Seminole State has taken the unusual but necessary step this week to withdraw Mr. Zimmerman from enrollment. This decision is based solely on our responsibility to provide for the safety of our students on campus as well as for Mr. Zimmerman." Zimmerman was enrolled in an associate in arts degree in general studies.
