What American 'Political Prisoners'?

Mr. Bauer didn't name any of the "political prisoners" allegedly held in America's jails—because there aren't any. So is this a case of Stockholm Syndrome? Perhaps, but Mr. Bauer likely came to his views while earning a degree in "Peace and Conflict Studies" at Berkeley, if not before. On a website calling for his release, a friend attests to his "strong critic[ism] of the US-led brutal war on Iraq and Israel's ongoing violence against the Palestinian people."
