You are confusing the rights of accused persons in England with hose of accused people hare.The law says you have the right to a have a jury of your peers.
The Magna Carta guaranteed that lords would be tried only by lords, while in this country we have the right to a fair and impartial jury.
I wonder what the verdict would have been if a farmer or two had been on the jury.
Are you suggesting that farmers might condone murder?
