I have to agree with you, Giok. Rejoicing in Tookie's execution would make me no different (as a person) to the Palestinians rejoicing in the streets after 9/11.

It's nothing to do with legality - the execution was legal; both the letter and the spirit of the law were observed.

Rather, it is to do with morality and ethics, and the law is very distant from that, it serves a different purpose. Nevertheless,
"When life you have taken, no matter the reason,
the man that you were, you no longer can be".

"Thou shalt not kill" has a full stop after it. Not a comma and "...except...".

What Tookie did was abhorrent legally and morally. What the state did to Tookie was legal. That's all.
