I saw a picture of a trashed cyber cafe (near the Place de Republique). All the computers were gone. There was one broken monitor on the floor. I do not believe the claim of no looting.
I think some of the blogs out of France also dispute the no looting claim.
I distinctly recall reading in the first week that there was looting. It's beyond the point where a guy has to jot down reported facts and watch for them to be left out later in the week's reporting.
I watched a German news interview of a French guy, whose car was lit up. The guy had only liability insurance on the car. There is no one standing there to pay him back for the car being gone. He is extremely bitter about what they did and the fact that the French government rewarded them with 35 billion Euro of support....and he got nothing. He has a point...I'd be in Muslim neighborhoods...looking for payback.
