Bob Brown is always right there where he's needed, whether it's standing in front of a bulldozer or doing time in a prison cell for his beliefs. He has had his car blown apart in a forest and his life threatened countless times. He is always a calm and thoughtful man and always a gentleman. We can bet, that when he became a disruptive voice against Bush there was a very compelling reason.
As a postscript to the incident - the Tibetan and Chinese guests of the Greens, who were not included in the ban that applied to Bob Brown and Kerry Nettle, were at first prevented from attending at President Hu's speech. They were finally sent to the glassed-in area usually reserved for school children, which is without intepreter facilities. Bob Brown and Kerry Nettle did not try to oppose their ban.
