At the Berlinale Film Festival last February there was a gala event sponsored by BMW called Cinema for Peace. A couple of protesters decided to protest against BMW and other carmakers. "Cars cause war. BMW should stop making cars before throwing peace galas".

My favourite sub-title is:
"You must move away from here. You cannot sit here like this."

"But if we move we cannot protest. So we can't move."

Now THAT'S logic. ;-)
