Of course we do. There is no way on God's earth that those boys could have disappeared without the King' connivance or knowledge. You might as well re-bury Hitler in full ceremony.
Jackdaw, the programme pointed out that the Tower was under the control of the Duke of Buckingham, who was however secretly transferring his allegiance from Richard to the future Henry VII.
The princes had been declared illegitimate (because their father was already married to someone else), so Richard had no particular reason to get rid of them. But it might have suited Buckngham to kill them and blame Richard, to boost Henry's case.
As an ex-history teacher I remember this well. Richard III featured in a booklet called 'Problems of evidence'. The thesis was that because there was no proof which would stand up in a court of law, Richard should be acquitted of all charges. This was when revisionism was at its height. My reply of 'load of b****ks ' was not well received by my examiners.
there was a lawyer (American) on the show too: he reckoned the prosecution wouldn't stand a chance. You do need evidence.
The best new evidence the show offered was from David Starkey: he'd discovered that when Tyrrell (the supposed killer) was tried, King Henry and his wife (the princes' sister) went along to watch. From this he deduced that something important, like a confession to the murders, must have happened. And, er, that's it.
Let's put it this way. Richard III was an evil little s0d, who sucked up to his elder brother, Edward IV, but happily connived in the killing of his next brother, George, Duke of Clarence. On Edward's sudden death seized the opportunity to grab the throne. Infanticide did not stand in his way.
