I have mixed feelings on this kind of thing...
For instance, state highway patrols are paid as good or better than county deputies and city cops... But a state Fish and Game warden - A sworn LEO every bit the same as any other, and even more alone than any of them in his duties, gets paid way less. And Corrections Officers working for the county - I know they ain't sworn, but a lot of times they should be. And i doubt any of em come close to the danger and rough and tumble that COs do for pennies on the dollar...
Same sort of things with firemen. They are in a very high-risk job, and likely should get paid accordingly,
As an instance, I like the idea of a sworn state LEO being able to move horizontally between services, be it warden, highway patrol, marshals, and etc, not to mentioned being cross-trained.
