Indeed.
Every agency has a budget, and to get what you need from the budget means doing what you can cheaper. Qualification with training ammo is NOT cheaper because of the potential of lawsuit after a shooting that went wrong. You train with training ammo (much cheaper), and qualify with carry/duty ammo, then ensure each officer/agent has just enough fresh duty ammo (varies by agency from one to a few boxes) periodically.
Whining about govt waste/fraud/abuse is great fun, though, so lots and lots of folks never let facts get in the way.
Example - my last Fed job required frequent/extensive international travel to undesireable places. A buddy from my state-level policing days heard I was traveling to places he'd never heard of and immediately assumed I was living high on his tax dollars, flying first class. Sorry, my friend, but flying first class is only for folks with specific, provable medical conditions verified by a doctor acceptable to the Feds - besides, most folks don't want to fly Cebu Pacific, Air Malaysian, Iraqi Airlines, or Moldovan Airlines to fine places like Cotabato City, Sandakan, Basra, Chisinau, or Podgorica.
