Picture the situation. I am at the front of a traffic queue at a red light. You're in your police car immediately behind me with your siren going crazy and your blues flashing. I just sit there, waiting, waiting, waiting for the lights to change. Meanwhile someone, perhaps one of your colleagues, is getting murdered. Still I just sit there, waiting for the lights to change (mainly cos Ken Livingston has programmed the lights to be as obstructive to efficient traffic flow as possible, but that's another story). As is often the case, there is no cross traffic.You still say I ought not 'break the law' and edge forward thru the light?
