I do not doubt their existence at all. I agree, that information would be carefully given. Even if the president demanded a tour, they would explain
to him it is a 4 level facility or something, then tour those levels, show him a few diagrams 'proving' it is only 4 levels, and then take him back
to his nice plane, so he can tell the people it is just a normal research lab.
Of course, really the bad things might be going on on the extra 3 levels or so, which might even have secret entrances from the other higher level,
making even employees unable to get to them, not like a button on the elevator covered by some tape, but rather a secret door under a carpet in the
cheif scientists office or something.
