There was an interesting Channel 4 news item in which the Chief Constable of the British Transport Police said his officers weren't prepared for a chem/bio attack and didn't know what they were facing. They went in regardless (respect). I can't find a link but it may be repeated elsewhere or in the papers tomorrow. Does this mean that the large-scale exercises involving people wearing inflatable green suits are largely window-dressing to reassure/intimidate the public? If the bombs had contained a credible survivable and dispersable biological agent (admittedly a very unlikely scenario) then much of London would be now be puking/sh!tting/coughing their guts up/out. I assume that there is an intelligence-based threat posture, similar to the systems those of us in uniform were familiar with. Buf if there is no int (and no foreseen threat) then that creates an unenviable dilemma for an incident commander - does he/she send the troops in to save life and perhaps succumb or become a carrier, or hold them back as people are dying?
