How long until wolves appear

[Prepaday]

The riots last year...From London to Manchester in the space of 2 days if I remember rightly, then spread like wildfire everywhere else the next day and there was no BIG reason for it, someone got killed and this gave all the idiots an excuse to go looting, I imagine if the shit hits the fan and it is announced that Britain has no cash, we can see it happening a few hours after said announcement.
Again, the looting will spread like wildfire and nowhere will be safe.
