Kelsey Griffin, Bletchley Park's director of communications, said the exhibition was likely to avoid any mention of Snowden. "It is not within the remit of Bletchley Park trust to make political statements," she said. "We are very much a heritage institution and involved with education. So that will be the focus of the cyber-security exhibition – drawing lessons of the past for the future."

Museum consultant and Bletchley Park trustee Hilary McGowan said the trust had not directly discussed Snowden. "We have discussed cyber security and its importance in the modern world – that's as close as we've got to discussing Snowden and what he's done. I'm not sure acknowledging him would be the right thing to do, that might imply we approve of his actions."

So....we longer approve of those who risk life and limb to tell the truth about their government. Hmmmp.
