Why are there only six people on the Zimmerman jury? nt

The Supreme Court has held, in Williams v. Florida (1970), that the right to trial by jury doesn’t require the traditional jury of twelve people; six suffices. (Ballew v. Georgia (1978) held that juries of five or fewer are unconstitutional.)

Nonetheless, while many states allow six-person juries in misdemeanor cases, very few allow them for very serious felonies, such as murder, for which Zimmerman is being tried. According to Bureau of Justice Statistics, State Court Organization 2004, tbl. 42 (supplemented by this statute, only Connecticut and Florida provide for a six-person jury for very serious but noncapital felonies, and only Florida provides for a six-person jury when the offenses is punishable by life imprisonment (with or without parole); Utah apparently provides for an eight-person jury; all other states provide for twelve-person juries. (Again, I’m speaking here of very serious felonies; a few more states provide for six-person juries for less serious felonies as well as misdemeanors.)
