"Trayvon Martin armed himself with a concrete sidewalk and used it to smash George Zimmerman's head."

Said the defense attorney, in his opening statement. Meanwhile:

Prosecutor John Guy's first words to the jury recounted what Zimmerman told a dispatcher in a call shortly after spotting Martin: "F------ punks. These a-------. They always get away." Zimmerman...  viewed [Martin] "as someone about to a commit a crime in his neighborhood.... And he acted on it. That's why we're here... He shot him for the worst of all reasons: because he wanted to.... Zimmerman thought it was his right to rid his neighborhood of anyone who did not belong."
