After listening to several of his calls about black suspicious teenagers matching descriptions of robbers in the neighborhood, I have to wonder if every time a teenager walked down the street looking a certain way, he thought they were "suspicious". Could he have seen Trayvon and his cousin or friend before, since he mentioned to 911 that they would be back near the back gate? GZ says he has seen them before to 911. Could these fellas have been innocent also and GZ always saw a law breaker in everyone he saw? He certainly seemed to be overly annoyed by small children at play in the neighborhood. Maybe his problems were authentically more serious, adrenal exhaustion or something, than we have considered. His voice tone in the calls always sounds calm, yet his words just don't seem to sit right.
