The story come from the NewsNight Blog of BBC Radio 4.UK with title "The doors mistaken for political extremists in 1968".A new information talking about "things know and unknow" of Jim Morrison and things in between the Doors , i clipped this article to post on my Yousaytoo journal following a new serie mix video on Youtube to story telling " A death behind the life music of Jim Morrison the doors front man".
This is a real story ,just listen now :
Jim Morrison, the Doors at the time of "The anti-Vietnam war demonstration of March 1968".
As the press reports became more lurid, Mary Whitehouse, moral campaigner, was issuing telegrams to the Met Police. One calls for "something to be done about " BBC Radio Four's "The World This Weekend" after it interviewed protesters.

Another says this:
From: Mrs Mary Whitehouse - To: Ch. Supt. Special Branch.

I have received information from an American friend of mine that an organisation called "THE DOORS" who are a political extremist organisation, are now in England...With the student plans for demonstrations next month, I do not think that their arrival here in the United Kingdom is a coincidence...

Yes, Jim Morrison and the Doors - in England at the time for a drugged-out concert that can still be seen on Youtube, even if Newsnight can't afford to show you the official archive (!) - were mistaken for some kind of revolutionary group. Actually, when you consider their impact on music, culture, fashion and the general androgyny of the next 40 years they probably were revolutionaries - though the worst they inflicted on the establishment at the time was a stumbling press conference at the ICA.
The day time
As the demo approached the final police precautions were put into place: a Major Biddle and three other police explosives experts - until then engaged, Dixon of Dock Green-style in safe cracking exploits - were bunked up at Cannon Row police station for 48 hours in the run up to the event. From the documents it is clear they were there to deal with high explosives, not petrol bombs: a separate team was to deal with these. So spooked were the authorities that they set up the first bomb squad, at least a year before the formation of the Provisional IRA and the Angry Brigade.

In the end the demo passed of much quieter than the previous one. A breakaway group headed for Grosvenor Square and clashed with police but the vast mass - theatre critic Ken Tynan estimated 110,000 - stayed in Hyde Park to hear speeches. By this time, many colleges, including the LSE were occupied and Tariq Ali's radical paper "Black Dwarf" was urging "All Power to the Campus Soviets".The police log of arrests and incidents for the day looks puny now: one German was arrested with an air gun and some dope; a man was found in the stables of a barracks, allegedly preparing to sabotage police horses. There were three Molotov Cocktails discovered - they were handed in to the police by a demonstrator at the Cenotaph on Whitehall, just yards from where Major Biddle and co were keeping watch.

As ol' Jim Morrison hismself said: Strange Days!
I repeat : Jim Morrison hismself said: Strange Days!. At that time,he doesn't do anything more same as did a mistake for political connection that may have a force helping to get out the court in the near 1969.

About The demo and today
Especially ,continued with a short post of Newsnight ,blog of BBC.UK.
The demonstrators were a bit lightweight compared with today, nobody was seriously attacked or hurt. All in all a really unremarkable day.
Demonstrator Ian Birchall that you seen his action on the video mix, now in his sixties, tells me, "now, on top of an illegal war we've got climate change as well...I want to smash it even more!"The Secret files "Autumn Offensive".Information, a stack of police files relating to the much bigger anti-war demonstration of October that year. Watch tonight: they tell a story of rising panic in the establishment: the creation of Britain's first bomb squad; an intelligence feedback loop between Special Branchand the press that ramped up the tension; and, farcically, the rock group The Doors being mistaken for a group of foreign revolutionaries...
The anti-Vietnam war demonstration of March 1968 was a turning point in post-war politics: it turned violent right in front of the world's media; the police were shown throwing punches into the faces of already arrested students, and in general losing control. The police files from that event are considered too sensitive to release.The Vietnam Solidarity Campaign demonstrations, it's easy to forget, were not just anti-war: they were overtly supportive of the North Vietnamese side in the war with America. But Newsnight has obtained, under Freedom of Information, a stack of police files relating to the much bigger anti-war demonstration of October that year
Fearing a repeat of this, we now know, from the Secret files, that the London Division of the British Army offered to assist the Met during the so called "Autumn Offensive". An offer that was declined, though it was discussed also at Cabinet level.Everyone can watch BBC archive footage of the 1968 protests from link address and this Video Footage of anti-vietnam protest 1968 to this post .
