Photography and Image Credits

I have used supplemental images in addition to my own photography while creating this project. Reasons for this include time constraints, unavailability of evidence I could photograph, and cases where certain images would give a better explanation to a situation than my own narration. Unless otherwise noted, pictures are filed under Attribution-Share Alike 3.0 Unported.

All supplemental images were taken from the Creative Commons, a non-profit website that allows images to be taken and used within copyright laws.
