Bang. The door to your cell is shut. You have survived the arrest, you are mad that you weren't more careful, you worry that they will get others too, you wonder what will happen to your group and whether a lawyer has been called yet--of course you show none of this. The weapon, the fake papers, your own clothes, all gone. The prison garb and the shoes they've thrown at you are too big--maybe because they want to play silly games with you, maybe because they really blow ''terrorists'' out of proportion in their minds--and the control over your own appearance taken out of your hands. You look around, trying to get an understanding of where you'll spend the next few years of your life. Prison Round Trip was first published in German in 2003 as ''Einmal Knast und zurck.'' The essay's author, Klaus Viehmann, had been released from prison ten years earlier, after completing a 15-year sentence for his involvement in urban guerilla activities in Germany in the 1970s. The essay was subsequently reprinted in various forums. It is a reflection on prison life and on how to keep one's sanity and political integrity within the hostile and oppressive prison environment; ''survival strategies'' are its central theme.
