He left there to pursue a career in commercial aviation in the north of Canada. From there hejoined the Ontario Center for Microelectronics, a provincially funded research and development center. Bill left there for a career in the military as a civilian contractor at what was then called the Defense Research Establishment, Ottawa.

Over the years, Bill has acquired extensive knowledge in the field of technical security, and he started his own company in 2010. That company is called William Pretty Security Inc. and provides support in the form of research and development to various law enforcement and private security agencies. While this is Bill's first book, he has published and presented a number of white papers on the subject of technical security. Bill was also a guest presenter for a number of years at the Western Canada Technical Conference, a law enforcement only conference held every year in western Canada. A selection of these papers is available for download from his website. Read More Read Less
