The man accused of killing teenager Treyvon Martin took the stand this morning. George Zimmerman was in court for a bond hearing, and took the stand briefly, where he expressed regret over Martin’s death.

I am sorry for the loss of your son,” Zimmerman said to Martin’s parents. “I did not know how old he was, I did not know if he was armed or not.”

Thanks to Florida’s sunshine laws, the hearing was televised live and in full on the “big three” cable news channels. A judge set the bond for $150,000, with a GPS ankle bracelet for monitoring.
