My 2 cents - go the police officer route, fly on the side and if available go into piloice aviation. From Pro Pilot mag it seems to be a growing segment of law enforcement.
I'm not a cop or nurse but have relatives who are cops and my mother (plus 3 aunts) has been a nurse since 1970.
One is a PHL detective (17 years) and the other is a state trooper (5 or so years). Both love the their jobs because its not regular 9-5 but complain just like every other joe schmoe. They make good cash have nice homes and their wives/kids are happy. They get to tell me good stories at xmas too.
The nurse thing is hard. While pay can be good I've really seen my mom slow down the past few years. Granted she has been in intensive care for 38 years almost all of it full time. She has been at the same hospital for the past 20 years so her sked is pretty good. no weekends and 3 days a week (12hr shifts) for 40 hours pay. its a tuff thankless job though. It is also in demand now because of the ageing boomers but what happens in 10, 15 or 20 years when the boomers and greatest generation is all dead - less demand. I always see bad guys around with the growing gap between the ritch and poor. Look at PHL for example - whenever the ecomomy craps or a rep is in office the city goes to sh1t like it have been for 8 years. Crime in PHL is thru the roof. they need cops bad.
Just my 2 cents
I'd love to get into aviation part of LE. Especially flying helicopters which is something I'll probably never be able to rationalize (the expense) otherwise. Plus still flying and you don't have to deal with as many deadbeats.
