Man, San Fran sounds a lot more fun than Seoul.
Though Seoul has protestors who are willing to turn flame throwers on the police as well as attack them with their own power hose (Youtube it. You know you want to). Being a peace loving soul however, a 1000 person pillow fight sounds more fun.

Hmm. I'm comparatively new to Boing Boing, so maybe the discussions of 180 degree phase shift networks and cyanide come with the territory, but I have to say I do take a very different angle. And hence if someone put one of those things up in a neighbourhood I lived in, I'd do the following:
Call the local rag, tell them they'll have a good story for tomorrow's edition if they come to said location at said hour. Find a sledgehammer. Hold a brief press conference in which I'd state the following:
"I think the above gizmo is illegal under international law, and here's why: Article 33 of the Fourth Geneva Convention. 'No protected person may be punished for an offence he or she has not personally committed. Collective penalties and likewise all measures of intimidation or of terrorism are prohibited.'
Yes I know that is meant to apply to war time scenarios, but if the above are bad in wartime, I'd say they're a damn sight worse in peacetime. I therefore feel entirely justified in taking a sledgehammer to the above.
Thank you for your attention."
And then I'd go and have a pint.

"Does not have a position on this issue"?
They're a bit shite aren't they?
How about "it's collective punishment and we think it fucking stinks."
