For every "1" that got bitten in the arse there's 100 that got away with it. It's the decision made at the time and this is usually done on experience or stupidity. If the stupid one gets away with it it's put down to experience and if the experience one comes a cropper then it's put down to stupidity.. .. .Rules are there to follow and they will always be bent. They should never be broken. Its experience that has written them and it's a shame, in some cases, that experience won't update them.
