Recruiting high quality candidates for LE (and the CAF) is a challenge over the past five to seven years. The pool of candidates drawn to the profession - despite the better than average pay and benefits - is diminished by the ridiculously long hiring process (>2 1/2 years in my agency, for example). Many otherwise excellent candidate find something else and move away from LE. Some have no other employment options and stay in the process only to find the job isn't for them.
And, then, there's these guys who make it through al the hoops and end up giving their agency and the profession a bad name.
Two candidates I trained for my agency were arrested about two years after graduation as part of a drug investigation (internal conspiracy). As their former instructor, that was a real gut punch.
