People posting from the US may be under the impression that 1st Amendment rights to free speech are recognised by the Australian courts. They're not. Any right to free speech in Australia is based on common law, and has a considerably narrower purview.
Australian courts can and will rule mistrial if either jury or witnesses can be shown to have been suborn or coerced.
And please spare the ad homs. They're not relevant to critical thinking.
Anon can say or do what they like, so long as it's outside the Australian jurisdiction. Reason for my concern is what may transpire at Australian pickets.
