(CNN) -- George Zimmerman, the Florida neighborhood watch volunteer at the center of a national firestorm over racial profiling, crime and gun rights, gave his first television interview on Wednesday, saying he had to act after Trayvon Martin said "you are going to die tonight" and reached for Zimmerman's gun holster. Zimmerman sat for an interview with Fox News host Sean Hannity and expressed his regrets to the parents of Martin, 17. He said he is neither a racist nor a murderer. Zimmerman has been charged with second-degree murder for shooting Martin in what he says was self-defense. Martin was unarmed when he was killed in February while walking back to his father's girlfriend's house in a gated residential area of Sanford, Florida.
