IMO I hope Zimmerman is found guilty - I agree this is a tragedy, but I cannot agree with the state law. I do not find it acceptable to shoot under circumstances where common sense should have prevailed. IMO There were too many missed opportunities for Mr. zimmerman to retreat, and to keep himself away from his perceived eminent threat.
Trained gun owners, especially those carrying permits to conceal weapons should know the laws. Mr. Zimmerman has said in a TV interview that he knew nothing about SYG, which if it is true, he should never have passed any gun safety or training course, or should have been granted a concealed weapons permit.
MY OPINION Always, My Interest is always gun safety first!
