Re: death penalty
I'm sure that many of us have heard this quote from William Blackstone an English judge in the 18th century.
"It is better that ten guilty persons escape than that one innocent suffer"
The actual numbers used are immaterial, it is about erring on the side of caution. Just in case a mistake has been made.
On the continent of wild endeavour in the mountains of solace and solitude there stood the citadel of the time lords, the oldest and most mighty race in the universe looking down on the galaxies below sworn never to interfere only to watch.
