They've been having their little "talks" since the start, and nothing has ever come out of them.
But that is a result of a heavy police presence more than anything restricting what they talk about, and even the time they have.
I remember reading in the Telegraph that a legislation was soon to be passed (if it hasn't already) about restricting bikie gangs from congregating. Tell me how we expect bikies to sort shit out, if they legally aren't allowed to meet? Not that laws have stopped them in the past, but can you see my point?
The reality of it all, is that if they started the issues, they should be able to end the issues.
On a side note, I didn't previously see a mention about the gang 'Notorious' who are a major factor in these wars, yet are not "bikies". They are, as far as I am aware, a criminal gang for the sake of crime, rather than a criminal gang for the sake of a gang as the bikies are.
