Yes. Another FReeper made mention of John Good, the man who did testify that TM was atop GZ raining blows down; BUT who failed to come to his aid. I wonder how well John Good sleeps?
With the corrupt unJustice system now foaming across America, what could John Good have done other than holler that he was going to call the police? If he had stepped into the fray and pulled the attacking man off of the man being attacked, the Floriduh unJustice system might well have gone after Mister Good! Angela Corey (Khouri) has shown she will ignore the law and cheat the system to achieve goals set for her.
I've thought about what could break up such an attack without physically entering the fray. One of those compressed air horns might have worked, sound at that DB level tends to instantly disorient. A pail of cold water might have cause a pause in the action. A can of bear repellant might have discouraged further activity. Spraying the two with a fire extinguisher could dampen the fight. But all of these notions are hindsight. I cannot fault Mister Good for not becoming physically involved. I would have done so, because I do not cotton to a much larger person pounding a smaller person and trying to kill them, but I cannot fault John Good for staying out of the fray. had I been in Mister Good's position, Angela Khouri would have been bringing me up on charges for knocking Trayvon senseless to end the fight. But you can't project that onto Mister Good.
