I left Guantanamo Bay much as I had arrived almost five years earlier -- shackled hand-to-waist, waist-to-ankles, and ankles to a bolt on the airplane floor.
My ears and eyes were goggled, my head hooded, and even though I was the only detainee on the flight this time, I was drugged and guarded by at least 10 soldiers. This time though, my jumpsuit was American denim rather than Guantanamo orange.
When we landed, the American officers unshackled me before they handed me over to a delegation of German officials. The American officer offered to reshackle my wrists.
But the commanding German officer strongly refused: "He has committed no crime; here, he is a free man."
Strange, I thought, as I stood on the tarmac watching the Germans teach the Americans a basic lesson about the rule of law.
We've just marked the 10th anniversary of the opening of the detention camp at the American naval base at Guantanamo Bay, Cuba.
I am not a terrorist. I have never been a member of Al-Qaida nor supported them. I don't even understand their ideas.
I am the son of Turkish immigrants who came to Germany in search of work. In 2001, when I was 18, I married a devout Turkish woman and wanted to learn more about Islam and to lead a better life. I did not have much money.
