How many non-military federal employees carry guns?

I can only account for some 120,000, combined in several law enforcement agencies and a few not s- law enforcement.. like EPA, NIH, FDA..?

but, I know thta HUD allows officers that frequent the 'projects' to carry (and rightfully so). Now the Social Security Adm has ordered 174,000 rounds of .357 SIG ammunition.. and obviously it isn't for resale... so how many Federal employee CAN carry, with or without arrest authority ? I'm guessing another 15,00-25,000 are allowed to carry weapons.

No wonder the government in DC wants to disarm the citizens! We are surrounded by armed Federal employees! And we have no idea WHY they carry and how they are trained.

They fear that we will discover who is armed and prepare to defend ourselves.
