wow, what the feck happened with that first paragraph????
n thinknig about it a bit more......i think that exactly what demo/event it is will make a big big difference to how swp operate. so when its a firefighters, anl, anti-war demo, they'll be there good and early, and even stay late maybe. if its an anti-road, greeny issue generally, they'll more than likely behave just as you say they do
