I wonder if you'll have the same sentiment when a Cac calls the police on you for walking with a hoody on.
Better to be safe than sorry
Poor example because the response to Trayvon was not appropriate. People shouldn't be afraid to call the police if something is of concern to them. People like Trayvon also shouldn't have to fear "justice" being taken into the accuser's hands or face disproportionate use of force from police.
There is no shortage of people, white or black, who put on hoods to commit crimes. Zimmerman's motives were not pure, but it's not a totally unreasonable suspicion that would merit calling the police.
And that would have been the appropriate end to the situation. Zimmerman was suspicious. He called the police. The police investigated. They realized Trayvon was of no harm to anyone. Trayvon was inconvenienced, but went home.
