Correct! This, from the article is wrong.
He followed the teenager despite being told not to by a police dispatcher and the two got into a struggle.
The dispatcher simply told him that following was not necessary because police were on their way. The dispatcher did not instruct him to stop following. Regardless, according to the 911 call, Zimmerman said "OK." and started back to his vehicle. On the way, Martin attacked him.
There is no way he should have been charged but he was because of the threat of mob violence. We will see more of this as the blacks are enjoying a taste of power through mob rule. Things will get hotter as we near the November election. Then Obama will declare martial law and suspend the election and stay in power until forcefully removed. I expect better from News Max.
