You didn’ listen to the part that preceded the part you quoted she told Zimmerman to keep an eye on Martin not once but twice. If she had just told him twice to keep an eye on Martin, why would she then turn around and say we don’t
need to have you follow him,
It makes as much sense as Zimmerman making a racial comment to a person on the other end of the phone conversation, when he can’t tell the color of their skin. You may make an off color comment to a friend, but not to a stranger over the phone.
I listened to it several times. It does make sense that you would make a comment to yourself in a more hushed voice while on the phone. I do it all the time.
I think he said 'punks.' 'Punks' is not racial.
