My local motorway, the M1, was closed, in both directions for most of today. This evening the security services were confirming that a corrosive substance had been found, but apparently no explosive material. I'm guessing that the forensic and hazardous materials specialists have done a good job, and that whatever evidence there is has been collected correctly. However, little thought appears to have been given to the public caught up in the queues of vehicles on both the north and south going routes. Eventually, the police were arranging for trapped vehicles to turn round and leave the M1 in some sort of controlled fashion, but this operation didn't appear to start until well into the afternoon for an incident which started before 08:00. Why such a delay? Are we that short of Police, or is considering peoples' basic needs not in the rulebook? Did the Emergency Services themselves have toilet facilities at the emergency?
