Where do the private security guys get their guns? Are corporate arms allowed? Also, who can loan a gun to a contractor?
The bona fide security contractors don't have problems getting arms.
Those that work for .....burton... generally don't get one.
But many a soldier or marine has offered a sidearm outside the wire 'just in case'. Totally unauthorized, but when you're on Tampa or Uranium or Mobile, your make your own rules to take care of yourself.
Most will never need one. Those who need one are probably already in over their heads.
