I hate the current situation. HOWEVER there can be few people who face with the "We're not sure but we think it's possible" answers on day one wouldn't have banned liquids. It would be a bloody brave man that said no, in the full knowledge that hundreds might die. I see where we are, I see why we're here, there's hope for some gentle back tracking in the future. But at the time, it would have been a terryfying decision for the DfT. Hindsight is 20 / 20 .
