War on drugs is "universally unconstitutional" (tags)
The reversal of the onus of proof in drug-possession cases is incompatible with the rule of law and is therefore unconstitutional in ALL jurisdictions. If you're a juror in a trial for possession of a prohibited drug, and if you are told that the "law" requires the defendant to prove that the possession was unwitting, it is your civic duty to put the onus of proof back where it belongs (on the prosecution), raise it to the proper standard (beyond reasonable doubt), and hand down a verdict on that basis.
The worst drug-criminals are legislators (tags)
An Australian court finds that the existing drug laws, by reversing the onus of proof, violate the presumption of innocence. But all convictions stand. To any legislator who willingly allows the reverse onus of proof to continue, I say: May it please God that you become a victim of it.
