I don't know of any place where you can get the information across the board, but I'd be happy to send you the union pay scale from Minnesota. It starts at about $45,600. My sense is that that's comparatively good. I thank the Teamsters.

I was an intern in the Orange County CA PD office last year and in an exit interview I had with the program director they showed me a copy of the pay scale for PD's in their county. A new PD starts at $65K roughly and it moves up from there at a significant rate each year. After about 5 years the scale was just over $100K. And the actual PD makes just under $200K. Not bad for PD work.
In Albany County, NY, the PD is also an attorney in a law firm. I don't know if he makes the same as the DA (130k) but I do know that starting p.d's make 32k (and its a part time position with all of the benefits of full time work). I think that's pretty good too.
