You also state that it is now acknowledged that parading the naked body of the fallen king into the streets of Leicester was "shameful." ( and possibly done when Henry Tudor realised the King had scoliosis and bending his body over a horse made this more apparent to the populace - evil body - evil mind).
"We can't undo history but we can learn from it.." you state. Really? All evidence to the contrary.
So why then the constant perpetuation of that image throughout everything done within the recent plans around Richard's re-interment . The image occurs three times ( to date) Once in the "Towards Stillness" installation. (I notice this was roped off yesterday - frankly I am not surprised as I wouldn't want any children of mine careering into sheets of metal) Then there is the planned window in the Cathedral, and it is also depicted in the visitor centre. Would once not have been adequate?
I can think if several historical figures who were killed in battle/executed and whose mutilated remains were displayed at the time, but who are not depicted in this way now, irrespective of what you think of them. Displaying images of Richards corpse is singularly unusual as figures like Simon de Montfort or Wat Tyler are not depicted dead or dismembered.... And they WERE technically traitors who revolted against the English Crown.
I also note that you "guarantee" dignity. Well - you must have a different definition of that to most people I know. And in all truth - how can you "guarantee" that?
