WTF are administrative government organizations doing buying weapons and ammunition!?!! They have absolutely no business purchasing any sort of weapons or ammo whatsoever. This stinks to high hell and then some. An arms buildup may be them tipping their hand.
They have armed security guards at many of their facilities and have for years. One can debate the need for this (especially when there is already a security force run by another agency that is supposed to handle security for all administrative buildings), but it isn’t a grand conspiracy.
