I'm wondering about this, too. The DHS numbers are pretty big.

MG Curry raises some good questions.
I call "bullshit" on this retired general.

The Social Security Administration (SSA) confirms that it is purchasing 174 thousand rounds of hollow point bullets to be delivered to 41 locations in major cities across the U.S.
The ammunition will be shipped to SSA Office of Inspector General/Office of Investigations (OIG/OI) offices, located at SSA regional and field offices. Nothing sinister there.
No one has yet said what the purpose of these purchases is, though we are led to believe that they will be used only in an emergency to counteract and control civil unrest.
The pistol ammunition will be used for practice, qualification, and duty use by the 300 commissioned Federal law enforcement officers of the SSA OIG/OI. No one at the Social Security Administration has stated nor implied that this ammunition procurement is intended for use in "emergency to counteract and control civil unrest", so the statement "we are led to believe" cannot mean "The SSA told us". Who, precisely, led this retired general to such a belief, and why does he think the source is credible?
Pistols would not be the logical first choice for use of deadly force in response to civil unrest; if the SSA was actually worried about riots at their offices, they would order large quantities of .223 and 12ga ammo. Remember the principle of fire superiority, "don't bring a pistol to a gunfight".
Hollow point bullets are so lethal that the Geneva Convention does not allow their use on the battle field in time of war. Hollow point bullets don’t just stop or hurt people, they penetrate the body, spread out, fragment and cause maximum damage to the body’s organs. Death often follows.
Bullets are lethal. Every time a law enforcement officer pulls the trigger in the line of duty, it must be with the clear understanding that someone or something will
die. The officer's intent is to immediately incapacitate that someone or something, but the officer's foreknowledge is that death is the expected end state. Hollow point ammunition expands inside the body, transferring energy and disrupting major organs and tissue systems, with the intent to instantly incapacitate, and to
reduce the likelihood of overpenetrating and injuring or killing an innocent person downrange.
Do I really need to go on?
