The media are wittering on about the "Batman" protestor clinging to a ledge on the outside of Buckingham Palace.
Despite our almost continual constructive criticism of the Home Secretary David Blunkett, the Metropolitan Police and other "anti-terrorism" agencies and their policies, this is not something over which the Home Secretary should resign, and we would be astonished if he actually did so.
Even if the protestor was a terrorist, which he obviously is not, being trapped on the outside of the building, with no member of the public, let alone Her Majesty the Queen (who is hundreds of miles away in Balmoral in Scotland), within range of any possible explosive device, and with armed police containing the publicity stunt, there is no breach of security
The only danger is to the protestor himself. to whom the police now have a duty of care to prevent him hurting himself.
An architectural point to note, is that Buckingham Palace, exhibits massive stonework on its facade, especially on the ground floor, up to the second story windows, a reference to a Renaissance Italian palace with a "piano nobile", which rises above the hoi polloi and any potential rioters etc.
The "story" has all the prerequisites to make newspaper and tv media headlines, most importantly, the static "incident", in London, a major international news and media nexus, has been ongoing for long enough to send an outside broadcast crew (and in the case of one TV company, their ?1000 an hour news helicopter) to the "location" , with no physical danger to the journalists involved, and with adequate bars and public houses nearby for them to repair to, so as to write up their "exclusives".
The huge amount of column inches and prime time tv news interviews which the organisers of this protest are garnering for their cause, must inevitably encourage other protest groups to employ similar tactics.
The feeling of being manipulated by clever protestors and lazy journalists is an unpleasant one.
Neither was the idiot who attacked the security gates across the end of Downing Street with a sledgehammer anything to worry the the security authorities, who dealt with him very swiftly.
Much more serious was the alleged "burglar" who somehow got into the Northern Ireland Office at Thames House on Millbank, and then exited into the foyer of MI5 the Security Service, where he managed to attack two security guards with a machete, and who was then subdued by the police with a Taser stun gun weapon.
Even this violent incident did not actually compromise the MI5 building security.
