I spent 10yrs as a USAF SP... Most of my time was spent on the "Security" side of the house rather than "Law Enforcement", but I did some. My LE duty taught me very quickly that I do not like to meddle in peoples lives whether as a cop or not. I responded to a "public disturbance" once, nothing seemingly too serious, but the situation evolved into an attempted suicide before it was all over. Without going into any details, I'll say that there was nothing I could have done to prevent the incident, and it came without warning, even though, I still feel it was my shining moment as a complete failure. I'd hate to have to deal with that (possible) kind of thing daily, especially the ones that go sour.
Just something to think about.
