2.8 million rounds divided by 57,812 firearms only equals about 48 rounds per weapon, a rather surprisingly small amount, especially given the number of rounds many FReepes had before their TBAs that left them tragically gunless.
I noticed this too. Unless most of the 57,812 firearms are stashed away in evidence or testing/id collections, the FBI has a serious ammo shortage. Even if a 10th of the firearms are active-duty, they have an ammo shortage.
I wonder if they categorize some firearms as “active” and others as “reserve stock” in storage? That would give a higher ratio of ammo to arms.
