Hal Turner is not a plant, he's not an informant, he's not a freedom fighter, he's just a hack. He doesn't work secretly with anyone, nor does he know anyone in power of any type. He's just some guy that makes an internet radio show out of his basement with delusions of grandeur.
People paying attention to him and what he says just feeds his delusions.
There are no REAL Amero coins in circulation. Those that you see on the internet were ordered by private citizens so they could stir up opposition of a North American currency. Do you really think that they are going to mint sound money when they consolidate their power? No, that would take away from their power.
Hell, if the Amero was a currency that has inherent value like that, I would support it.
