Ah, bikies. Always a colourful debate. I've met some nice, friendly ones and I've been offered to be shown the sharp edge of a plate glass window by others.
Someone I know had a friend who was shot dead by some of them. They went to pick something up, it wasn't there (and it wasn't the friend's fault) so they shot him, maybe for the inconvenience?
Something that someone who knows told me once was that heaps of the base-level crime (beatings, extortion, blackmail, slanging etc) that is committed by clubs is actually carried out by nominees, or noms with the orders handed down from above. These are people who want to join up but are going through their testing phase before getting the mark. A lot of them are too stupid, have loose lips or light fingers to be useful as members so they are used for a while as cheap labour and then discarded.
I remember a while back some nominee or other fled from the police after they saw him running a red light on a motorbike. He threw away about 5 ounces of meth before crashing and being caught with another 20. Was a courier and had to run a red light whilst carrying... that's the kind of stupid shit that you hear about that is almost always attributed to nominees.
Life experience: Don't cross them and you'll be relatively safe. Never borrow money from them. Never get drugs "on tick". Never talk shit. Never make promises. Opt for the Russian system of business: Deals are made in the present, not the past. Speculation can kill you.
I wonder how these Control Orders are going to pan out? Someone I know knows two people that have them and it hasn't slowed them down one bit.

. Anyway...
About the death penalty for murder: I agree in principle but only for certain types of the crime. A murder that is a crime of the heart, provoked or spontaneous can't be treated the same way as a planned, organised one. I agree with the ultimate punishment for someone who, for example, kills another person over a pair of shoes but not for someone who kills, for example, spontaneously over a crime of passion.
For both sides of the argument: There are people in US prisons awaiting execution who will die, but are innocent, and it raises that old question:
Let 10 guilty men go free to save 1 innocent?
Or kill 10 innocent men to kill 1 guilty?
Peace.
