Lang seemed have a thing about 'the baying mob' and the consequences of an irrational emotional response backed up with the power of groupthink.
Superb deconstruction of a complex situation and an incredibly thoughtful conclusion. Reminded me a bit of M, but playing the issue so much further. Genius. In my top 5 films, would love to have a seen a Hitch interpretation of the story, but still using Spencer Tracy, or maybe Jimmy Stewart , but not Cary Grant. Not sure he would ever bettered Fritz Lang's version though, some things are best left..
