Left and Lefter has a good piece on Scott Parkin, the American peace activist recently detained and deported from Australia. Asher attended one of Parkin's workshops on protest tactics, and notes that the methods taught there were both legal and effective. He speculates that curbing the spread of such tactics may have been the Howard government's motive for deporting him. I'm not sure that I'd give them that much credit. Unfortunately, because the Australian government is under no obligation to reveal their reasons, even to Parkin himself, we'll simply never know.
