Unfortunately, politicians and governments lie, or at least want to promulgate a version of the truth, as they want it to be.
Usually foreign news correspondents are banned from a country, when it's citizens can no longer be intimidated to 'speak through a flower' (not publicly criticise the government). This frequently accompanies widespread and overt Human Rights abuses. It is then, that these people's voices need to be heard and must be heard. The truth must never be allowed to be hidden and those with the courage to proclaim it gagged. Anything that aids this, is IMO fully justified.
The liberty of every person on this planet, depends on our willingness to say what needs to be heard. For when governments only wish to hear, what they want to hear and ignore what they need to hear, then we are all in trouble.
