WOW, a triple play!
Known a lot of cops in my day - some good, some bad, some on my side and some determined to bring me down. Been my experience that the ones who grew up wanting to do the right thing became the good ones. Others grew up getting their butts kicked on a regular basis and are using their newfound power to get back at the world. Cowards with badge and a gun. Been in a few situations where the good cop had to put the bad one in his place!
Unions - no problem with the concept, but as a former union member who has spent the past 13 years as a management Labor Rep. , there are some on both sides who're just determined to push the envelope. Same thing, the ones who used to get their butts kicked now use their position in management or the union to stir up trouble. Those without an axe to grind understand that National Agreements work both ways.
Smoking - quit 10+ years ago and still stand downwind to get a whiff, but let me choose when that is, please.
