Suspiciously is in the eyes of beholder. Him being in this case a neighbourhood busybody, nosey parker, and a wannabe cop, who once called 911 about children playing in the street, another time about a stolen bicycle (by black teenagers) which wasn't stolen, his judgment of suspiciousness was itself suspicious, and we know that it was suspicious to Martin, to whom he did not identify himself as a self appointed Captain of an unregistered Community Watch. Your hero Zimmerman himself behaved suspiciously, can't you at least admit that?!
“to whom he did not identify himself as a self appointed Captain of an unregistered Community Watch. Your hero Zimmerman himself behaved suspiciously, can’t you at least admit that?!”
Zimmerman was not required to identify himself. How could he? Martin ran, and Zimmerman lost him.
He was self appointed? The Neighborhood Watch didn’t appoint him captain? Proof?
Unregistered Community Watch? Do they need to register with someone? Proof they didn’t?
Again wild accusations and speculation.
If Martin did attack Zimmerman as Zimmerman returned to his truck (as indicated by available evidence and statements) then he obviously wasn’t threatened.
The burden is on those who are questioning Zimmerman’s actions to prove he did anything criminal.
Crickets.
