Nope, unless they can prove he was not acting in self defense, they can not convict him of jay walking!<quoted text>
I would blame the prosecutors for overreaching. Manslaughter/negligent homicide would have been appropriate charges.
And you still have no even tried to explain what crime GZ committed before he shot Trayvon. Zimmerman did not break his own nose, knock himself to the ground and bash his head on the side walk and Trayvon was not standing over him to help him up either!
