We had the G20 here in Pittsburgh last year. They practically shut down the city. Downtown was closed down and boarded up. They closed the schools, and something like half the population had the day off from work.

The police cracked down seriously on anybody who even looked like they might protest for weeks before the conference. They're still trying to sort out the people who were legitimately arrested from the young people from the Universities who were just in the wrong place at the wrong time.

We wound up with some broken windows and a damaged ATM machine. On the last day, there was a nice, peaceful, protest. I'm all for peaceful protests. Apparently everyone cheered the Falun Gong.
