Sallow
The Big Bad Wolf.
He followed him around the complex in a car, then got out..and was following him on foot, and then he gave chase.
This isn't trivial. He was carrying a gun at the time.
Where did you hear he "gave chase"? Never heard that Zimmerman went running after TM. Many people carry a gun. That is irrelevant since there is not evidence the gun was out of its holster at the time Zimmerman was on foot. Let's stick with the facts and stop assuming.
You hear it on the 911 tape. Catch up.
