Just read this on the "What are you Watching" thread and thought I'd start new thread rather than derail it.
Watched this on the Princes in the Tower from last year on Channel 4. Interesting example of presenting strawman, and false dichotomy, and Robert Rinder appearing to prostitute his 'expertise'.
Note, there is not enough evidence to decide that Richard the Thurd murdered the Princes in the Tower but despite the way that it is presented in the programme that's not been the position generally taken. It's been highly questioned for a long time.

While it is true that there is no "smoking gun", Richard III is far and away the most likely candidate for ordering their murder. In fact, as the person usurping Edward V, if it wasn't Richard, he almost certainly would have got around to it sooner or later. It was simply too dangerous to leave them alive.
He also had easy access to the princes and plenty of lieutenants prepared to do the deed for him.
Most historians of the period would agree that it was probably Richard III that did it.
