Remember the Sequester? The president is claiming its budget cuts will inconvenience travelers by squeezing essential services provided by the (opulently armed and stylishly uniformed) DHS. Quality ammunition is not cheap. (Of course, news reports that DHS is about to spend $50 million on new uniforms suggests a certain cavalier attitude toward government frugality.)
Spending money this way is beyond absurd well into perverse. According to the AP story a DHS spokesperson justifies this acquisition to "help the government get a low price for a big purchase." Peggy Dixon, spokeswoman for the Federal Law Enforcement Training Center: "The training center and others like it run by the Homeland Security Department use as many as 15 million rounds every year, mostly on shooting ranges and in training exercises."
At 15 million rounds (which, in itself, is pretty extraordinary and sounds more like fun target-shooting-at-taxpayer-expense than a sensible training exercise)
that's a stockpile that would last DHS over a century. To claim that it's to "get a low price" for a ridiculously wasteful amount is an argument that could only fool a career civil servant
