That makes it sure sound like there were more involved than just 2 white guys.

This short audio clip on NPR suggest that more were involved. Kind of hair raising.

IIRC, it was Jayna Davis who said that the FBI had some 21 videos from security cameras around the are of the Murrah Building. She wondered why none of those videos had ever been shown to the public.

That audio indicates that at least one video exists of the truck and occupants (leaving) just before the truck blew up.

This case has many unanswered questions, and no one in a position of power seems interested in finding those answers.
