"The corporate grip on opinion in the United States is one of the wonders of the Western world. No First World country has ever managed to eliminate so entirely from its media all objectivity - much less dissent. "Of course, it is possible for any citizen with time to spare, and a canny eye, to work out what is actually going on, but for the many there is not time, and the network news is the only news even though it may not be news at all but only a series of flashing fictions..." Gore Vidal

Oil paintings are probably the only evidence not introduced by party spin doctors as they tried to claim victory for their leaders – even the ones who weren’t there – after last night’s BBC televised debate of the 2015 general election. Yet looking at the debate’s closing image of Ed Miliband shaking hands with Nicola Sturgeon as Nigel Farage stands isolated to our far right, I cannot help thinking of some grand narrative painting of a moment in history.

This handshake has the formal, momentous quality of, say, the meeting of Dutch and Spanish generals in Velazquez’s painting The Surrender of Breda. Sturgeon seems almost to bow, as the Spanish leader does in that masterpiece of history painting. All it lacks is someone looking out of the picture, catching our eye, commenting silently on the falseness of the moment, the complexities behind a simple image of friendship and possible alliance.

Perhaps some will see that ironic commentator as Farage, who voiced his discontent with the event itself and the composition of its audience, and claimed to be uniquely addressing the real audience watching at home.

The US airport security agency is facing ridicule after leaked documents revealed its checklist of tell-tale signs that a passenger might be a potential terrorist.

Despite its own report finding that the human ability to identify deceptive behaviour through body language is no better than chance, the US government has spent almost $1 billion on a programme deploying Behaviour Detection Officers to airport security.

The specialised agents of the Transportation Security Administration (TSA) are taught to evaluate passengers based on a checklist known as the “Screening of Passengers by Observation Techniques” (SPOT).

But according to a copy of a SPOT report published by The Intercept, the “stress factors” that could see passengers stopped at security include arriving late for your flight, blinking too much, sweating and “excessive yawning”.
