Dr. Drew On Call

Unarmed Trayvon Martin was shot and killed last month by a neighborhood watch volunteer in Sanford, Florida. George Zimmerman made a call to 911 indicating that he thought the youth was up to no good. An operator told him not to follow the teen, but Zimmerman did anyway. Minutes later, Martin was dead. Zimmerman says he fired in self-defense. Martin was carrying a bag of candy and a can of iced tea.

Zimmerman is licensed to carry a concealed firearm. He is not a police officer, but aspired to be. Was he an overzealous enforcer? Was race involved as some have claimed? Does what we know about the case-and Zimmerman-reveal personality traits that might explain his actions?

Televsion personality Paula Deen’s recent disclosure that she has type 2 diabetes has created quite a frenzy as of late ... but HLN’s Dr. Drew has someone of different take.

“Paula Deen is entitled to confidentiality as it pertains to her health care,” he says. “She has no obligation to share anything about her health care with anyone … she’s advocating a certain culture and certain kind of eating. She’s entitled to do that … I just think our reaction has been too impulsive and unthoughtful.”
