Why was George Zimmerman not arrested the night of the shooting?
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.
