So, in true political glory, countries left right and center (well, mostly center really, mainly the US, UK etc) have ordered urgent reviews into procedures that never really worked against any criminal with a braincell anyway. Obama has ordered that people arriving in the US from certain countries will be searched. Some of you will think this makes sense. Some of you will cry "but good sir, that's like being guilty until proven innocent".
