There's so much bluff and bluster on this thread, it really amounts to little more than a hill of beans. ALARP is being bandied about with such abandon by individuals who either have a rather limited and simplistic grasp of the meaning of the concept, or are deliberately misinterpreting and overlooking finer points to advance their agendas.
Before forming conclusions based solely on what is discussed on this thread, I recommend anyone with a serious interest in this complex, important and emotive subject to have a long talk with a lawyer (with the requisite specialisms) on the precise definition of ALARP and all the legal caveats and nuances which can pertain to it.
It will shed a different light on most of what is written here.
