Now the SCOTUS sweeps the remaining evidence under it.
Interesting that they don't roll such tape on the evening news.
But you are correct again - I guess that the tape that once existed showed C. Livingston carrying out a rug, and Foster somehow got out of the most secure building on the planet without being caught on any video at all.
Who had access to those tapes anyway...(the killer and cleanup squad are known to the Secret Service, IMO.)
