Here's something to consider: the right to be tried "by a jury of your peers" does not specifically mean you have a right to be tried by a jury of people who look like you, go to the same church as you, or believe as you do. But whatever else it does mean applies solely to the defendant and never the Crown.
If memory serves, as inherited from the British, the principle originally meant that the jury would be drawn from the same social class you (the accused) were: nobles got a jury of nobles, and peasants got a jury of peasants. It wasn't exactly an egalitarian principle then, however nice it sounds today. It was institutionalized surrender to entrenched class distinctions. It [i]never[/i] meant a jury of the victim's peers.
It is also highly unlikely to ever be deemed, today, to include a representative component to any particular jury. "Peers" means, simply, fellow citizens.
