I'm going to offer some support for Stroller here (sorry, Col).
I was at Winchester railway station at 5:20AM yesterday morning to be confronted by two Polly Soffissers resplendent in their black paramilitary uniforms, baseball caps and each carrying a semi-automatic of some description. Not what you'd expect at a time like that in rural Hampshire.
Anyway, got chatting to them, as you do. Turns out they'd been there all night and were about to knock off. As far as they were aware there were no plans for a day shift to take over, but they'd been informed they were to resume that evening.
Given the modus operandi of your typical Islamic suicide bomber, isn't it a requirement that you have a crowd within which to stand and detonate yourself?
If I've got this right, and leaving aside the prospect that someone could plant a device overnight, wouldn't it be more helpful to see Polly during the daylight hours?
The two officers agreed with me, but were only following orders.
Of course, I pointed out, there's an election on.
"You got it!" replied Polly.
