Zodiac killer - The one and only credible solution to the Mt Diablo code

This video presents the one and only credible solution to the Zodiac killer's 50 year old Mt Diablo cipher Additional comment after forum discussion elsewhere: The focus on capital letters in this video does not come falling from the sky. The upper part of the Button letter in this video contains the clues for how to "read" the lower part. The capital letters in School Buss thus serve as a clue to search for the capital letters M and F in the lower part, just like the underscore serves as a clue for looking for an equation.
