—We know that a 911 dispatcher told Zimmerman not to follow Martin.—
Actually, no. The dispatcher told Z that they didn’t need him to follow Tray. Huge difference. Most men still would have followed.
Not to mention that a 911 operator has no legal authority to order anyone to do anything. Zimmerman was under no legal obligation to follow the operator’s suggestion.
I can't believe how many people hear these 911 tapes and conclude Zimmerman was told NOT to follow him. What the hell is wrong with people? It's been repeated by many on Fox News. And they call themselves professionals?
I will add, that you could make a case that the 911 operator was actually suggesting Zimmerman follow Trayvon but was just covering his backside by saying "we don't NEED you to follow him" at the same time implying it's ok if you do follow him as that will help is locate the suspect.
A perfect example of this was a recent case where a single mother shot and killed a man who was breaking into the mothers home with an accomplice. The mother was armed and asked the 911 operator if she could shoot the intruder. The 911 operator stated "I can't tell you to do that but you do what you have to do to protect your baby" (not and exact quote but close). In other words we can't tell you to shoot this guy but if he gets in shoot him.
