NASA Facility Under Lockdown

A NASA facility in Ohio is currently under lockdown after reports of suspicious activity involving a possible gunman. It has been reported there has been a possible shooting in building 77 of the facility, and local police are not involved. The location has more than 3,400 employees. If that was me, I would think with all we have gone through as a nation, it would be impossible by now to get a weapon inside a government run facility.
