Yep. This strengthens my suspicion that Sullivan was Zodiac. He took cryptography classes but it didn't make him a bonafide, certified, expert cryptographer, just an amateur. Again, the mental illness aspect fits the bill....in his delusional mind, those classes made him an expert.
Just imagine the rage that consumed him, when Donald Gene and Bettye June Harden cracked 408.
