So the Rozzas have found a few of the great unwashed with ... 1. Weapons- but what exactly, a kitchen knife and a poker? 2. Replica weapons - Great like to see how that would have panned out .See how long they last against the Secret Service when tey bean eaters pulled out even a spud gun lookalike. 3. Some nasty litrature- Oh that would put the fear of GOD into Obama. 4. Other stuff? So how would you stop London for the G20? I'd go for . 1. Liqify Lion shit and spray it near the Police horses - It would be like the Kentucky Derby down the Mall. 2. Trick a few 100 W.I. to help by spiking the tea that they will be serving with a vast dosage of Ipcac syrup. 3. But 10,000 old cars and arrange for them to all break down at the same time near the summit. Instant grid lock. Any others?
