Do you think 'they' know something we don't?...
I'm not sure reading this would prevent the sort of people who'd panic from doing so but I suppose we have to be seen to be doing something. Anyway, I'll be doing what I did during the IRA years and not altering my movements one jot.
I dare say that right now the 'chain of command', decision making process and escalation procedure is being reviewed and shortened. Terrorists apart, nobody wants dithering to cost lives.
