George Zimmerman, the 28-year-old man who shot and killed Trayvon Martin, has been an in-and-out student at Seminole State College. Now he is out–expelled by the college. Why did Seminole do this? Zimmerman is certainly in a lot of trouble, but he has not yet been convicted, tried, indicted or even arrested. Did the college hold some sort of rigorous but unpublicized hearing? No. Did officials, too impatient to wait for a trial, just conclude he was a murderous racist? No, that doesn’t seem to be the reason either, at least judging by the statement Seminole put out. Here’s what Seminole said: Zimmerman was expelled because of “the highly charged and high-profile controversy” surrounding him. He generated emotions and publicity that made the college uncomfortable. This shows that small colleges can be as unprincipled as great ones (Yale, Duke) in acting without principle, procedures or any attention at all to student rights.
