1) How old was Trayvon Martin and how much size difference was there between him and Zimmerman? Initially, old photos of Trayvon Martin were shown in the media that made him appear to be about twelve years of age and Zimmerman's weight has fluctuated dramatically. This has given many people the erroneous impression that a grown man was fighting a child. In actuality at the time of the incident, Trayvon Martin was a 17 year old, 6’2, 160 pound football player while according to his friend Joe Oliver, Zimmerman was 5'8 and 170 pounds. In other words, Martin was younger, 6 inches taller, more athletic and the more imposing of the two men.
2) Why was George Zimmerman not initially arrested?: According to the Sanford Police Chief at the time, Bill Lee, who has since lost his job over this case,
When the Sanford Police Department arrived at the scene of the incident, Mr. Zimmerman provided a statement claiming he acted in self defense which at the time was supported by physical evidence and testimony. By Florida Statute, law enforcement was PROHIBITED from making an arrest based on the facts and circumstances they had at the time. Additionally, when any police officer makes an arrest for any reason, the officer MUST swear and affirm that he/she is making the arrest in good faith and with probable cause. If the arrest is done maliciously and in bad faith, the officer and the City may be held liable.
The police department needed to do a job, and there was some influence — outside influence and inside influence — that forced a change in the course of the normal criminal justice process.
