Was cycling one of those small access roads that straddle the very large main roads. There was a wall between that and the main road. A police van and fire engine were blocking the road, and it was cordoned off with tape. I went on the pavement, very slowly, walking pace. But the municipal police stopped me and asked for my passport. I didnt know what was going on so I just gave it to them, I should have said I dont have it with me. So they fined me. I dont really know the rules in paris, I asked them but they didnt explain them to me. My travel companion did the exact same thing as me, but wasnt fined. I feel like it was entrapment a little bit. Also, it took a while, so I smoked a cigarette, knowing this policeman was an arse I knew better than to toss the butt on the floor. But I had to put the thing out on the floor rather than my own bare skin, and the bastard tried to fine me for that even as a was putting the butt in mp pannier pocket.
