"...Any journalist passing through London’s Heathrow has now been warned: do not take any documents with you. Britain is now a police state when it comes to journalists, just like Russia is. In this respect, I can say this to David Cameron. Thank you for clearing the air on these matters of surveillance. You have now demonstrated beyond any reasonable doubt that these anti-terror provisions are capable of rank abuse. Unless some other facts emerge, there is really no difference in kind between you and Vladimir Putin. You have used police powers granted for anti-terrorism and deployed them to target and intimidate journalists deemed enemies of the state."
