No doubt. The first couple of days will give them an idea of what to expect from the police and MSG security. President Bush is undoubtedly the main target for their disruptions. They'd like nothing better than to upstage him.

I'd really like to see an investigation into "rent a protestor". Most of these kids have no idea about why they are even there. Somebody (from the Pickle Foundation?) must be paying them to be there.
