Go do 900+ hours in the academy and then tell us about the gravy train.
You clearly don't understand how things work. Lots of departments FORCE guys into working 2 shifts - 16 hours. You're right, no one is twisting their arms, because they don't have to - if they don't work the double, they're fired. Ever work 5 16 hour shifts in a row?
The classic line is "these guys put their lives on the line daily." Which I don't disagree with, but there's more than that.
They're risking being sued every day - one wrong move, well-intended or not, could be their last. How many days have you had like that? Recently heard a story about a state trooper that got SHOT during a traffic stop. He returned fire, shot the guy 8 times, but both lived to tell the story. Guess what happened? The Statie gets dragged through a 9 YEAR lawsuit for excessive force.... AFTER GETTING SHOT to start the whole thing. Sounds like fun, right?
Also, they're often the first to show up when YOUR life is on the line - this includes EPO too. When someone is lit driving home and hits a tree and goes into cardiac arrest, guess who is most likely the first responder giving CPR? When someone drives their boat into a jetty, guess who's responding and giving first aid (I know for a fact that some Coast Guard boats don't even have an EMT bag, so don't bother saying the coast guard).
When dispatch gets a call for a well-being check for grandpa, who lives on his house boat, and hasn't been heard from in 2 weeks, guess who's responding? Guess who's finding grandpa decomposing and covered in maggots?
I understand the initial thought of seeing a LEO working a detail and thinking its too easy, but you need to think about what he/she has to deal with during their normal shift of work. It is outside the realm of what 99% of the country deals with at work.
