I agree, and I agree that Mugabe is a thug.
However, you said it all: He and his photographer sneaked in and was "trying" to report the truth.
The "people's right to know" ends with our OWN government and our OWN country. NOBODY has the right to violate the laws of a soverign nation, just because that nation is ruled by a thug.
By your measure, an Al-Jazera reporter has the "right" to enter our country illegally in order to write a report on our security precautions... and we have no reason to arrest or imprison him.
Is our nation ruled by a thug? He looks so sweet and cuddly!
