Been there, done that
IMO, law enforcement is both a calling and a lifestyle, that has been mentioned above. I went on a number of ride alongs before going into the academy at the young age of 18 and graduating #2 in the class. During 1 of the ride alongs, the cop who I was friends with and riding with, got involved in a very violent shoot-out which opened my eyes to a different world. I loved it and coped with it pretty well.
It is not for everyone. I was in LE for 5 years and it is a good thing I wasn't in any real relationship at the time because it wouldn't have lasted. It is very strenuous and I don't think 95% of spouses understand the toll it takes, which leads to fights, drinking, cheating, etc..
I got out of LE for a number of reasons, even though I LOVED it. Main reasons being: getting shot at sucks; going to grand juries sucks; working some of the worst streets on the east coast USA by yourself with no partner will test your physical and mental toughness and can get very crazy very quickly; seeing friends killed in the line of duty; having recurring dreams with a terrible outcome; money is OK but not commensurate with duties; I found myself becoming a very non-trusting, cynical, confrontational bastard and I didn't like who I was becoming neither did some of my best friends who decided they didn't like it either; etc.
I found the best parts of the job to include: being part of a brotherhood that has a very strong bond no matter where you go; doing something that really matters and really does help people most of the time; no day is ever the same; free meals; drinks, lap dances
with badge; finding myself in the role of a father, doctor, psychologist, lawyer, life saver/protector, and sometimes someone's only friend...all in just one day's work.
If you have to pay for the academy yourself, start saving unless you have cash to hold you over for 5 months. You will not want to have to work 8 hours at night after spending all day in the academy, if it's anything like where I went through. Start at 6:30am - finish about 4 or 5pm. Then have 2-3 hours of homework or typing all notes, like we had to do. You can see where not only will you be tired and honestly probably not do well in the academy because of that, but you won't see your family that much. If your wife is cool with that and you paint the entire picture for her to see, including the fights and hardships that will come after becoming LEO, then go for it. Like some said, it is a very rewarding personal career but understand what you are getting into.
I left it and do regret it from time to time but I know I made the right decision in the long run.
And if I spelled a few words incorrectly and forgot some punctuation or other grammatical errors, then please all the anal grammar nazis correct me immediately :banghead: :banghead:
