There is no special skill or requirements to be a LEO....
Do tell! However, I understand based on discussions with long time LEO's that departments have a terrible time filling LEO positions due to applicants not meeting the "no special skill or requirements". Funny how that can be.
Can't speak to Iowa but in MA there is a long waiting list. A waiting list of Brothers, Sisters, Cousins, Nephews, Uncles, Friends, Hacks...
Nepotism is destroying the LE profession.
