I started learning to fly almost 40 years ago, been flying continuously in one capacity or another since then; been a cop for 33 years; and been an airborne cop (helos and F/W) for over 10 years now.......... and I have advice for anyone looking for a job as an airborne law enforcement officer, and I don't mean this to sound harsh, but it is the truth:
You better want to be a cop first and a pilot second, or.....
(a) We don't want you;
(b) You probably won't make it through the "street time" to the point where you become competitive to get an airborne law enforcement spot. These are usually are highly coveted assignments; guys on my Dept generally have 8 - 10 years on before they are considered "competitive" for selection to our Aviation Unit. And ...
(c) There's a good chance you won't like the job if you get it.
If you are really interested in this line of work, feel free to PM me.
