This episode rang a bell while I was watching it and when I googled it, I realised why. The idea is based on a true story that was reporting in the media in March 2009.

As a story for this show, I think it worked really well. It really makes you think, though, about the assumptions the CSIs have to make about the way they work and the equipment they use. Although the threads of evidence they cling to are so fragile in one sense, they can still pull the investigators way off track with relative ease. When they also have to contend with a legal system that could seize on a screwup like this to cast doubt on all their evidence, the pressure becomes even clearer.
