Experts Says it Will Be Hard To Refute George Zimmerman's Claim of Self-Defense

Charged with second-degree murder in the shooting of Trayvon Martin

(CBS)—Among the strongest evidence in George Zimmerman's defense may be George Zimmerman himself, several experts say—in part, because it may prove difficult for prosecutors to refute his claim that he killed Trayvon Martin in self-defense.

Zimmerman, a former neighborhood watch captain, is charged with second-degree murder in the shooting death of the teen during an altercation in February 2012 in Sanford, Fla. His case  is set to go to trial Monday, June 10.
