I read a piece of news online says Plymouth police officers in England make more arrests
and reduce violent crime by wearing a helmet mounted camera. (

Interestingly, the other night when I watch CNN tech news, a police officer being interviewed concludes at the end of the video footage with a big smile on his face “it saves us a lots of paper works”. It is amazing how system being viewed and used by different stakeholders. To the public or tax payers, it’s all about the purples of having police department; to the executives in department, it’s the numbers that make them valuable; to the first line officers, what makes it worth is the convenience of concluding his or her day by simply changing hat and enjoy more time with family.
