it's An Interesting Debate Hella
I will add this caveat to the alcoholism. A lot of it has to do with the hazard of their professioin. Cops drink plenty too. In fact many give up or lose their careers because of it. Do you remember the Jessica McClure story with the little girl in the well in Texas? That was a successful rescue. If you saw what happene to one of her rescuers, Robert O'Donnell, as a result of that event, you might look at it a little different. He saved her life, but ended up giving up his own. This is pretty typical in the profession, although not for successful rescues.
