I really like these images by spanish artist Valero Doval, especially the colours in the one below.
HERE is a great link to some amazing photos of crime and punishment in the first half of the twentieth century. Some of these are incredible (some are just a bit grizzly too.)
Also the second volume of I Am The Friction is underway...it's a bit different from the first and may well involve a few more people. Keep your eyes peeled for it sometime in spring.
