Don't hire pilots anymore. You are an agent first, and a pilot second, maybe. They fly C182's, Citations, Caravans, some 210's, G-5. Gotta get on as an agent first and hope to get one of those slots that 80,000 people apply for. It's a lot of different kinds of flying and sometimes extremely boring.
DEA also does the same thing, except you have to be an agent for 3 years before flying.
If you want to fly, get into something where flying is primary. If you want to be in law enforcement and fly some, then you might check out the Airborne Law Enforcement Assoc and see what you can find out.
