Paarmo, I spent thirty years in the police, albeit in a different jurisdiction. I cannot think of a single instance where I would have chosen "freshly-trained but without experience" over "experience", either as a constable (in your ranks) looking for back-up or as a Sergeant detailing people to get the job done.
Would we take a freshly trained Air Traffic controller and let him/her loose in London Control, or take a CPL out of flight school and thrust upon them the full responsibilities of AOC work?
Hmm, didn't think so. But why not - it's that funny little thing called "experience"again, isn't it?
