First the article mentions big brother...
Still, Bill Dobbs of United for Peace and Justice, which has planned a massive anti-war demonstration on the eve of the convention, called the sound system "a potential Big Brother nightmare."
Then the article mentions this
"a new fleet of motor scooters to cut through gridlock should trouble arise."
When big brother starts using mini scooters, you know that is when you should be scared. /sarcasm
Notice how they did not use the word mini, they had to use the word motor to make them seem more big brotherish.
