Someone should remind him of the tactics used in Europe to fight dissidents... particularly in the Old Empire, where there is no written constitution, there are no enumerated rights, and all that keeps citizens from being ground under the heels of the Crown's lapdogs is the meme that modern Britain is reformed -- a nicer, gentler, psuedo-republic of a monarchy.
Stone has no desire to be careful when wishing for those things, of course, because such rights violations would provide him even more fodder for uninformed attacks against his own government which, worthless as it may be, is the least worthless of a sorry lot.
Why do news agencies insist on preserving pronouns and such inside quotes just to extend the quotes? What's wrong with, "Oliver Stone Says He is 'Ashamed' of His Country?"
