Too many of the paid staff that I worked with had broken families. Law enforcement careers are not easy on the family and that is the primary reason that I opted not to pursue it as a full time occupation. In hindsight though, with the state of things nowadays, I am quite relieved that I didn't continue down that path.
A US Marshall once told me, "It's a noble profession", and I wholeheartedly believe that - if only everyone would see it as such. These days, not enough of the good ones are staying in that profession and too many who have no business in uniform are filling those voids. It's messy.
