The BBC edited out these comments when broadcasting this interview.
This isn't a "benefit of the doubt" situation. This is an example of a highly influential person who is close friends with powerful people being allowed to continue his horrific crimes for decades. This isn't even a controversial opinion, it's widely accepted that Savile was protected. His 1974 autobiography contained admissions, there were plenty of accusations, when you have people making accusations and self-written evidence to support those accusations, you've at the very least got an investigation. That didn't happen, and it's not because someone was on a cigarette break or was too busy chasing robbers.
