My first reaction when I heard about the deaths of Jay Austin and Lauren Geoghegan was “what a pair of bananas”. They were killed while cycling in Tajikistan – which sounds as reckless as self-catering in the Congo – and left behind a manifesto of sorts that has been mocked as the height of liberal myopia. “Evil,” Mr Austin wrote, “is a ­make-believe concept we’ve invented to deal with the complexities of fellow humans holding values and beliefs and perspectives different than our own.”

On July 29, that thesis was tested and disproved when they were spotted on the road by men pledging allegiance to ISIS. The monsters ran Jay and Lauren down with a Daewoo sedan.
