Query: Lacks solid evidence to support claims.

Although the book made for interesting reading, I found it quite repetitive - as if arguing to convince reader of author's convictions. Lacked substantial evidence to confirm theories. Total lack of cooperation by LAPD and Federal agencies certainly adds to confidence in conspiracy theories as this book puts forward. Sirhan being a "Manchurian Candidate" seems to be more valid than multiple guns and/or assasins.
