mariomike, I believe, and I stand to be corrected by any of the LEO's here, that the difference among the cops is that they could easily find themselves conflicted if they were to serve as police officers in another organization/role. I further believe that the "two hatter" debate as you've quoted in your article represents firefighters alone as I have never before heard of the medics or the cops being rung up for this sort of thing. As well, the two hatter thing as it relates to firefighters is much a union thing, not a force stating that it's not on for I have never heard of that but am more than willing to hear it if someone has some dirt
As far as fire goes it is a complex and heated subject as one can see just by skimming the quoted article. I have my opinions for both sides and can see where both sides are coming from having served as both a paid and volunteer firefighter and having done both at the same time (though not a "two hatter" by the OPFFA's definition as my job was not union)
I could dish a lengthy and prepared document summing up my thoughts on the two hatter debate but it would add nothing to the thread.
