There's another element to a career in Law Enforcement, at least in my experience. Cops, assistant D.A.'s, etc...tend to become isolated in their social lives. That is to say... either it happens because of their friends' lack of appreciation of them, or their lack of appreciation of their friends. The lives become so different and a day at the office is vastly dissimilar.
So, at least in Chicago, cops, Illinois IBI (when it existed), State Police, and Local government attorneys tended to hang out together...after work...etc.
Other things I noted...and this is NOT a sweeping statement, just a personal observation...is that some substance abuse (alchohol mostly) seem to pop up, and a lot...LOT of marital discord and divorce.
just things to consider.
