... described by police as a "prolific, predatory sex offender"
The police are supposed to be investigators who offer their results of inquiries (if they can be believed) to a member of the judiciary, or an official inquiry/commission, and THEY make a finding and issue a decision.
With Saville it seems that all the normal procedures have been swept aside and the Plod have become investigators, judge and jury.
Whether the claims against Saville have been proven, or not, since the police have adopted a position against Saville, who has absolutely no one acting for him, their actions are to be questioned.
And why has it taken so long, by so many people, to find their voices? Surely one or two, or their parents, would have acted. It should also be born in mind that way back when Saville allegedly committed these assaults, "putting out" for favours was common.
Doesn't make it right but it surely changes the circumstances.
Chances are that the intended viewers, children, wouldn't even know who the character was supposed to represent, only these faux angry parents who love bitching about anything.
