According to aaranaardvark (Windsors On Cue For Panto.) the attack on Prince Charles's car, on 9 December 2010, was "an event staged by paid 'thugs' otherwise known as agents provocateurs as a pretext to introduce more draconian policing measures in the face of widespread and spreading civil unrest...
"We have already seen the Met playing around with these sort of false flag incidents like when they staged the fake 'attack' on a police van for the cameras early on in the student protest cycle... (AGENTS PROVOCATEURS - LONDON STUDENT DEMO)
"So we have the most expendable and least popular Royals deliberately attacked by police sponsored agents provocateurs while the Royal Protection Squad blamed their radios for failing to prevent the alleged "attack".....
"The chants of 'off with their heads' as the 'incident' took place actually sounded more like the Bullingdon Club 'scoundrels' than protest movement activists to me...
"How accommodating that the Royal car conveniently stopped apparently for no particular reason, to allow this to happen.
"The helpful 'bystander' who says 'the Duchess of Cornwall is being attacked' is entirely unbelievable.
"Nobody calls Camilla 'The Duchess of Cornwall'..... unless they are introducing her at an official engagement ....and that is what is indeed taking place here I think, whether she knows it or not?"
The 9 December 2010 attack on the Royals: the unanswered questions
From UK's Sunday Telegraph
1. Why choose a route through a violent mob?
Prince Charles's car drove up Regent Street 'despite the fact there had already been reports of vandalism'.
Roger Gray, a former diplomatic protection officer, said he was surprised there appeared to be no contingency plan for an alternative route.
2. Why did Charles travel in an old Rolls-Royce Phantom VI which is 'highly conspicuous and extremely difficult to manoeuvre'.
Unlike other cars in the Royal pool it was not armour-plated and did not have tinted and bullet proof windows.
3. Why did Charles's vehicle almost come to a halt once it reached the crowd, rather than driving through it?
4. Why were the limousine's windows actually open?
Pictures show the window on Prince Charles's side slightly ajar and the one on the duchess's side almost completely down.
5. Who was involved in attacking the car?
The main body of student demonstrators was being confined by police to Westminster.
6. Commander Peter Loughborough was the policeman appointed to head the Royal protection Command in 2003.
He is in fact the 7th Earl of Rosslyn.
