Chuck - thanks, I believe you're spot on. For a variety of reasons, the overwhelming majority of folks involved in basic training at FLETC (including for folks headed into exclusively "white collar" type investigative jobs) are former uniformed guys, so I think a lot of what gets taught is what worked/works on the street for uniformed guys. In fact, there is VERY LITTLE training done at FLETC where folks where anything but BDU pants and polo/t-shirt with a duty belt for all the "cop stuff" (holster, uniform style magazine pouches, baton/cuff/radio holders, etc).
I've long since given up trying to address programatic issues with my agency (when we approved Taurus pistols for personal duty weapons I resigned from even trying), but in my little corner of the world where I'm still sort of "king" on firearms and tactical training, I'll start easing folks into a different mindset...
