That being said, let this be a lesson to you as to what can happen when you elect to exercise that right even when you are right. You elevate the potential for disaster. Zimmerman may have been legally justified but look what happened. A young man is dead, a family devastated and Zimmerman risked life imprisonment for what? If he hadn't elected to carry a firearm that night he probably would have survived the fight, he would have been just as banged up but a young man would be alive and he would have avoided a murder charge and now the exile that he's forced to live in.
When you carry a firearm you expose yourself to a new world where run-of-the-mill altercations can escalate into a realm you never intended or anticipated like that. So be very careful. you're not a trained professional, you're not combat shooting qualified. This ain't TV. Comment.
