A person who willfully, maliciously, and
repeatedly follows, harasses, or cyberstalks another person commits the offense of stalking, a misdemeanor of the first degree
(Elsewhere on the same link)
“Harass” means to engage in a course of conduct directed at a specific person which causes substantial emotional distress to that person and serves no legitimate purpose.
Zimmerman both followed Martin (as he admitted to the police dispatcher) and harassed him (he caused Martin to fear that he would be raped, and he had no legitimate purpose in following him). He did so willfully (going so far as to defy police instruction not to do so) and maliciously (expressing the aim that the "coon" wouldn't "get away" this time). And he did so repeatedly (he followed him both in his vehicle and on foot).
How the hell does that not meet the legal definition?
Who's biased?
