At least one did:

"Juror B-37 says they found the law 'very confusing' but decided that they had to focus on the moments immediately before Martin was shot, even if Zimmerman instigated the altercation, 'because of the heat of the moment and the stand your ground.'"Here's the SYG portion of the jury instructions:

If George Zimmerman was not engaged in an unlawful activity and was attacked in anyplace where he had a right to be, he had no duty to retreat and had the right to stand his ground and meet force with force, including deadly force if he reasonably believed that it was necessary to do so to prevent death or great bodily harm to himself or another or to prevent the commission of a forcible felony.
Thanks for a very good post.
