I am at a loss as to what the problem is.
At my agency, each officer shoots 50 rounds per month at the range and qualifies once per quarter. On top of that, each officer probably shoot another 100 round per year practicing new drills. That comes out to 700 rounds per officer, per year. We shoot the same ammo at the range as we shoot in the field for reasons of civil liability. This way if someone sues us over an officer involved shooting, their lawyer can't claim we were unfamiliar with the characteristics of our duty ammo because we only shoot ball at the range.
I am going to assume the Fed follow a similar protocol. The article says the Feds bought 40,220,000 rounds. By my agency's standards that's enough annual practice ammo for 54,457 officers. So how many cops do the Feds have? Let's count -
8,500 Special Agents HSI
7,000 Deportation Officers & Immigration Enforcement Agents
21,370 Border Patrol agents
21,186 CBP Officers
4,400 +/- Secret Service Special Agents + Uniformed Division
295 Social Security Special Agents
I'm sure there are a lot more, but lets just go with these.
62,751 Feds X 700 rounds per year = 43,925,700 rounds needed
OOPS. It looks like the Feds didn't order enough ammo for everyone to practice monthly at the range over the next fiscal year. They are either going to have to order 3,705,700 more rounds, or someone is going to have to skip going to the range, or they are going to have to stop shooting bad guys in the field.
