You are suggesting that "arrested for assault" equals "guilty of assault".Martin was presumably erroneously followed by Zimmerman. Zimmerman wasn't walking down the street with pistol in hand and Martin didn't know he had a gun. Zimmerman was being severely beaten by someone. Martin was shot by Zimmerman.
The important question is: If Zimmerman would not have had a gun then who would of went to jail?
If you think that Martin would of been arrested for assault if he had not been shot then you must come to the conclusion that Zimmerman was legally justified in shooting Martin. The fact that Martin died doesn't change whether it was self defense or whether Martin committed a crime by attacking Zimmerman.
There must of been blood on the concrete if Zimmerman's head was being bashed on it, I am sure the police checked that at some point. Martin's knuckles indicate that he most likely punched Zimmerman. There were no marks on Martin to indicate that he had been hit.
And we do not know who touched whom first. cn
