Recently I have read an article on forensic science and I remembered my module done on it last year. Below is a brief summary of the article and my feelings. I realised how much these enrichment courses can indeed be applied to our life despite us not knowing.
Scientists led by Todd Pataky at Shinshu University in Tokida, Japan, showed they could identify individuals with 99.6% accuracy by the way their bare feet strike the ground in a paper published in Britain's Journal of the Royal Society Interface.

Using 3-D image processing and a technique called image extraction to analyze the heel strike, roll-to-forefoot, and push-off by the toes among 104 volunteers, the scientists proved the theory was sound. Next they will examine if similar results are possible when the test subjects wear shoes.

Pataky said the technology would be useful in security checks, but only in situations where an individual wants to be recognized, since people can consciously modify their gait.

From this article you can tell that it is very easy to identify a person using this technology. Anyone commiting a crime can now be easily identified if he unknowingly leaves a footprint behind. This would allow the police to trace the cu;prit more easily. However, it also has its disadvantages. The culprit can easily modify his gait such that he would not be traces. It also has not been tested if it works with shoes on. If it does not this might not be very useful as most people would usually wear shoes.  This is still a major improvement in terms of forensic science and now the police have an additional method to track down people.  

This article is reminding us how now technology is so advanced that it can be used in forensics in order to reduce crime rate and help the police.
