All over the TeeWee and internet, people are still talking about Zimmerman "disobeying" the 911 operator. Zimmerman did not "disobey a 911 operator", even if such a thing were possible.
The 911 operator asked Zimmerman if he was following Martin. Zimmerman replied in the affirmative. The 911 operator said, and I quote: "We don't need you to do that".
My roommate says "I'm going to the kitchen, I'll bring you a Coke."
I reply "I don't need you to do that."
She brings me a Coke anyway. Has she "Disobeyed My Orders"? According to every talking head on my television screen she has, and the meme is penetrating my frickin' computer now.
Besides, the whole concept of "disobeying the orders of a 911 operator" is ludicrous on its surface. Last I checked, the 911 operator is not in my chain of command. That's like "disobeying the orders" of your plumber. (Similarly, if your plumber suggests that it might not be a good idea to flush the toilet right this second, you'd be well-advised to take his suggestion under consideration. I'll bet George wishes he had.)
