Its just not the job it was though. Just like the Army. I cant speak for navy or RAF but I guess its the same.Better off joining the City of London police. No grief. They are the lead Force for financial investigations. After 10 years with your F.I. courses, your CV packed with evidence and contacts in the city, side move into a well paid job with a big city firm as a FI in their Fraud Dept.
Fraud Investigations are all mainly slow time anyway without too much grief, just a case of following the money.
H&S, gender, worries about being to harsh, human rights nonsense...all conspire to make it a shit job for anyone with a sense of fair play, fortitude, morals, values and standards.
