If I could wave a magic wand at the television screen and took the viewpoint of Dana:

  1. Mona would have been sent to a tropical island with 4 security guards or thrown back into her PhD program.
  2. Bilac would have been sent to a non-creepy psychiatric care/detox
  3. Given Mulder and Scully about 30 tasers
  4. People would have been gravitated toward each other so no one would ever be alone
  5. People would remember light switches are a thing.
  6. The policemen would have been LOOKING at Bilac.

Good episode, though.  :)
