Are there too many specialized positions in LE?

A few weeks ago, an article called "The 'SWAT nod': How to tell other cops what your duty assignment is without saying a word" ran on PoliceOne. It was essentially a list of how to make it clear to everyone in your department (as well as any other department) what your duty assignment is. In this week's podcast segment, Jim and Doug discuss when it makes sense (and when it doesn't) for departments to have specialists like SWAT, Motors, Narcotics, Foot Beats, Bicycle Patrol, Marine Units, Equine Units, and the like.
