Ah, that's alright then, as long as we treat the journalists ok.
There are of course isolated incidents, such as the detention of David Miranda at Heathrow, Sami al Haj an Al Jazeera journalist who was arrested in Pakistan, interrogated by MI5 and packed off to Guantanamo for 6 years, and Martin O'Hagen who was murdered by Loyalist paramilitaries, who of course, were in collusion with British security services.
You are right though, Britain generally does not kill or imprison journalists, we are after all, the good guys right ?
Of course, we're quite happy to hand over journalists and dissenters to other regimes known for their less than liberal treatment of opposition voices.
