I rode the subway in Paris , France in around 1972. They calls it the Metro. But one night I was going back to my hotal and the sharp well dress man was in front of me and as we came upon this other man this other man pulled a big knife on the well dress man. The well dress man did not slow down he just pulled out a gun and keep on walking. The knife man backed up and held his heart then he looked around and ran past me and I got on the train. I thought it was a street play but I know it was not it was real. after that I know subways way darge places at time. thanks for looking and comments and votes
