Zimmerman has a ccw permit.<quoted text>
Why would he be telling dispatcher "I don't know if i should be telling you this"
We don't know if Martin slugged Zimmermen first or if Zimmermen slugged Martin first.
How do we know if Zimmermen asked "What are you doing here"? Zimmermen also was not supposed to be carring a gun there to begin with.
There was nothing wrong with him being armed.
