     For an American, or a foreigner here, any chance to have a social life is welcome. But

what happened last night made me think I may be better off having no life while I'm in

Baghdad.

     Friday evening,l was on my way with an American journalist friend to his welcome party.

When we got to a checkpoint,we were told to get out of the car to be searched,which is

normal procedure. We waited under a tent,as our car was examined on the other side

of a wall. We couldn't see what was happening but we figured we would hit the road soon.

     But the search was taking longer than expected, probably because of a car bomb

threat that had been reported earlier. Then we noticed the officers put their helmets(头盔)

on. Never a good sign.

     Our Iraqi driver then noticed that our other Iraqi driver and guards who were in a

second car were standing facing a wall. We had gotten separated from them at the

checkpoint. We told two American officers that they were with us. They whispered

with each other and then walked away.

     A few minutes later, an officer walked toward us and asked us to follow him. He

said to me, "If you make any moves,l will take you down hard. "

     That's when l knew we were actually thought to be doing something terrible. We

were told to sit in a row on the sidewalk, facing the street. I noticed across the street

were our other driver and guards. They were also in a row, but in a kneeling position

with their hands on their heads.

     I was shocked. The only explanation could be that our guards had been at the

shooting range in the morning, so the police dog may have picked something up from

that. I also wondered why our Iraqi fellows on the other side of the street were being

treated worse than us when it was our car that was under suspicion(怀疑) .

      After the end of the hour long suffering, we were allowed to leave. No longer in

the mood for the party,we all went home.
