The questions you ask are, I expect, the very ones to which the IPCC is trying to find an answer. I suspect the answers may include cumbersome RoE and Release Procedures for your first question, or a good old-fashioned cock-up.
T o your second question I expect the "half-wits" had sufficient wits to realise that any sort of "warning" issued would trigger the very event they were trying to prevent.
All is not perfect, but it seems to me that the "bleeding hearts" really believe that we should give up policing suicidal terrorism. Which would signal the collapse of the State.
Could you now please answer my question? What would you have done if you were one of the "half wits"?
