Read Jayna Davis' book, she had enough evidence by page 6 as to a ME connection to convince me.
Yes, Bubba blamed the bombing on "hate radio".
I agree with your assessment of Jayna's book. A real eye opener for me as I read it just after the OU bombing... lots of eerie coincidences comparing her book to some of the research I did concerning names appearing in the press after the OU event.
