Pros: the chance to do various jobs and functions.
Cons: long hours, and days away from family.
The last position I held was the the Prime Minister Protection Detail, where our primary client is Canada's Prime Minister, and secondly his family. There I was part of the PM's Protection team, either as a Bodyguard, or Chauffeur in the Motorcade, in Canada, or wherever the PM went. When not at one of the previous functions, I was either the Bodyguard, or Chauffeur of the PM's family members.
At INTERPOL Ottawa, I was charged with assisting in locating wanted individuals from either other INTERPOL Bureaus, or Canadian Police Services.
I could say that what I enjoyed most was when I located an Internationally wanted "dangerous" criminal, and brought him to the requesting agency.
