The dispather said that they didn't need Zimmerman to follow the suspicious stranger and I've seen nothing other than speculation to suggest that he did anything other than to cease following him.
If you have a valid link, to something other than someone's biased opinion, I'll be glad to check it out and revise if necessary.
From what I heard it sounded as though Zimmerman was following him despite being advised not to. But of course I could be wrong. One side of the tape hardly tells the whole story. But I also got the idea that the whole thing probably was avoidable.
We shall see.
