Why does the government need that much non-training, highly lethal ammunition is the question.
@ FlemGem
Wadcutters are flat-tipped bullets used to punch clean holes in paper (hollowpoint and some full metal jacket bullets have a tendency to punch jagged holes in paper targets, making it tough to distinguish exactly where the shot hit for training purposes) for target shooting. Wadcutters are normally used exclusively for training, particularly with law enforcement. Wadcutters work best in revolvers, as the feed ramp of a semi-automatic can prevent proper loading of wadcutters. My point is that hollowpoints are rarely if ever used for training due to their higher cost and the fact that they do not punch clean holes, which is problematic for most training exercises that are dependent on accuracy.
"Also, do hollowpoints have some advantage in hostage situations where you don't want your bullets punching through the criminal/terrorist and hitting hostages somewhere else in the room? Hostage situations are not war, so using hollow points in such a situation would not be a breach of the Geneva conventions."
Hollowpoints *do* have several advantages over full metal jacket for law enforcement applications, including increased stopping power against unarmored targets relative to an FMJ round of the same caliber, and less risk of overpenetration (which could result in collateral damage as you pointed out). Most law enforcement agencies use hollowpoint or soft-tip ammunition for non-training usage. My concern is the sheer quantity and the fact that hollowpoint is not used for training. I saw a statistic that they have enough ammunition for a 24-year war (using the Iraq War as a benchmark for ammunition consumption rates)
Personally, I use full metal jacket exclusively, because A) My M1911 in .45 ACP will take down anything on two legs and most things on four legs in one round with ordinary full metal jacket and B) Hollowpoint (and wadcutters) do not feed reliably into 1911-style handguns without modifications to the feed ramp.

Hollowpoint is *not* illegal for civilian and law enforcement usage. It is simply illegal for use in warfare in the same way that it would be illegal to intentionally bomb a field hospital. In any case, hollowpoint is ineffective on the modern battlefield due to its vastly decreased effectiveness against even crude body armor.
My concern with the type of ammunition is that it A) is not intended for training use as claimed and B) they anticipate that their future targets will be unarmored i.e. civilians or poorly-equipped rebels.
