I love my hours, wages and most importantly job. There isn't another job like it anywhere. With that said, it's not for everyone in many respects. Some people can't handle the hours or the stress or some of the things we see and carry with us for the rest of our lives. Some people can't deal with others very well. Some of these things you find out before you get hired. Others you find out while in FTO or even, later on in the streets.
I've known a few people that quit in the academy, FTO and after working for awhile. Nothing wrong with that at all. It wasn't for them. With any job, you shouldn't do it unless it makes you happy. Money isn't everything, happiness at work goes a lot farther.
So do whatever makes you happy.
I find it easier to relate to fellow LEO's and have them as friends. It doesn't mean that I'm exclusive with the friends I have. As far as 'hardened'. Hmmm..not sure. I do know that I'm less likely to put up with **** now after doing the job for sometime, in comparison to the way I was before.
Be advised, I'm mean nasty and tired. I eat concertina wire and piss napalm and I could put a round through a fleas *** at 300 yards. So why don't you hump somebody else's leg mutt-face before I push yours in.
