I am formally retired but offer expertise on a part-time basis in the fields of anti-smuggling, fraud and organised crime. I have spent almost five decades associated with law enforcement. My professional career was with the Scottish Police Service (24 years) and the United Nations (UN) (14 years).

In 1990, I was awarded a Churchill Fellowship to study the role of law enforcement in mountain and ski safety and interacted with a range of agencies and volunteers in western USA and Canada. This led to the publication of a ski safety manual (now somewhat out of date) and safety campaigns in Scotland.

However, my police career then took me into the realm of combating wildlife crime and trafficking and this subsequently led to my work with the UN. My law enforcement-related activities have taken me to over 90 countries and territories around the globe. In many respects, my work has replicated the Fellowship – studying situations on the ground, learning from those operating on the front line, and then designing response strategies and raising awareness. I have written of my experiences in a book entitled The UN's Lone Ranger. My focus is now on organised crime in general.
