The real underlying issue where the military oscillates back and forth is arming guards. The security "issues" on a base are generally dealing with drunks, the odd protestor, and curious members of the public. A typical military base has a real security threat about once a decade. The rate of death/accident from mishandling firearms is a couple per year when guards are armed. It is an easy calculation. - I was a former weapons officer with responsibility for guarding nuclear weapons on a submarine.
