OK, so you are not comfortable with assuming time that we do not know, but you are comfortable with assuming that Trayvon knew the man was armed.Do you know if he first noticed the man while he was still on the call to his girl? Not sure we have enough information to know what he had time to do, but the call was apparently interrupted by the confrontation. If I were in the situation of being followed at night by a stranger, within running distance of my home, I’d not be waiting around for the police to come - that’s for sure.
There is a bias showing here. And it is not a bias toward the facts.
