Seems easy to understand, why it is a common belief among many, G Zimmerman should take some responsability for the death of Trayvon Martin.
A neghborhood watch person does not have the right to single someone out,(in my opinion racially profile them) pursue, confront, and end up killing them, on a hunch, without any actual law being broken before the confrontation.
Trayvon Martin also had a right to defend himself...
