Why Is Social Security Stockpiling Bullets?

Granny, get your gun? The Internet rumor mill has been buzzing in full force after the Social Security Administration posted notice of a recent ammunition purchase. Why would the agency responsible for pension and disability benefits need 174,000 hollow-point bullets?
Don’t worry: The SSA isn’t readying a militia. It is not — as the website Infowars.com suggested — preparing for “civil unrest,” nor hatching plans to turn on America’s senior citizenry. The bullets, it turns out, are for agents who investigate Social Security fraud. In a blog post, the agency noted:
Our investigators are similar to your State or local police officers. They use traditional investigative techniques, and they are armed when on official duty.
According to Jonathan L. Lasher of the SSA’s inspector general office, these agents make arrests, execute search warrants and carry .357 caliber  pistols. Most of the bullets — about 590 per agent for the upcoming fiscal year — will be used on the firing range.

Six hundred rounds per year for training, qualification and I would assume to carry on duty is not out of line at all,” said John W. Worden, director of the University of Missouri’s Law Enforcement Training Institute. “Hollow points are carried by law enforcement all over the country and are probably the preferred type of ammo no matter what caliber.”
Because they expand when they enter the body, hollow-point bullets are known to cause more tissue damage than other bullets. But hollow-points are preferred for duty ammunition because they stop when they hit an object instead of passing through it and striking more objects. LINK
