George Zimmerman leaves court with his family after Zimmerman's not guilty verdict was read in Seminole Circuit Court in Sanford, Fla. on Saturday, July 13, 2013. Jurors found Zimmerman not guilty of second-degree murder in the fatal shooting of 17-year-old Trayvon Martin in Sanford, Fla.

ORLANDO, Fla. — George Zimmerman says in a new video that a person in his circumstances can't feel guilty over surviving a confrontation like the one he had with Trayvon Martin, the 17-year-old teen he fatally shot three years ago.

Zimmerman said in the video made public Monday that he would feel guilty only if he thought he could have done something differently that would have saved both their lives.

Zimmerman was acquitted of criminal charges.

Zimmerman said he was speaking publicly now that an investigation by the U.S. Department of Justice is over. The video was released by his lawyer.

Last month, the Justice Department decided not to prosecute Zimmerman for a hate crime, concluding there was not enough evidence to establish that Zimmerman willfully deprived Martin of his civil rights.
