Re: 6 member jury, instead of 12- there is no magic about the number 12. In Florida, state law provides a jury of 6 EXCEPT in capital cases, where it is 12.
Your mileage may vary.
And if you are ever being tried by a jury, console yourself with the thought- your life is in the hands of folks that were not bright enough to get out of jury duty.
What we have here is... failure- to communicate.
