Ok, I am a college graduate with a masters degree in forensic accounting, and have worked for the Mississippi?

Wildlife Fisheries and Parks for 3 years. I am a Certified Public Accountant and a certified peace officer, i.e. im a game warden. Is this a good enough route for an agency like the FBI, Coast Guard Investigative Service, Secret Service, U.S. Marshals, and etc. I want to be a special agent.
if not, what other steps do i need to take
