Nothing to worry about because nothing is going to happen. How many times have we heard about " credible" intelligence saying something involving terrorism is going to happen? FA cup finals, royal weddings, just about every occassion in the last few years, where large crowds will be gathered. No doubt a few "al-qaeda" suspects will be arrested in the next few months, only to be later released without charge.

For some sailing dinghy's ?

Won't they notice at the start if one of the dinghy's has got an extra swarthy looking type on board trying to hide under the sails ?

Exploding horses in the dressage - thats the future.

Exploding horses in the dressage will take out 90% of the world royal families, all you need to do is feed a horse heaped spoonfuls of TNT for a few days before the event then slip a detonator into its haybag just before it goes into the arena, bingo, or maybe bang-go.

...or build yourself a real wooden horse, its been done before, and it worked.

It could be worse. The good lady newsreader on 6 music just reported that we are going to use Air to Ground missiles

It will be a bl00dy bloodbath

Watching the news this evening, my first reaction to the news that the FBI want to put their men on the ground was "Tell the yanks they can't come".

Fair or not?

You underestimate the threat to the minor royals and celebrities who take an interest in sailing. Plus there'll be the corporates from Henri Lloyd, Musto, Gil, Gull etc, all on their Sunseeker gin-palaces, flocking to get a bird's-eye (maybe gannet's-eye) view of the excitement. I think the fact that most sailing events tend to take place in the bloody sea, miles away from land, has escaped many who got all caught up in the excitment. I reckon the biggest winners will be Bausch & Lomb and any other manufacturers of binoculars. I still reckon I've got the best view of all - a 50" Panasonic HD plasma about 8' from my sofa

Last year, I was prevented from delivering a RIB to the Royal Naval Yard at Pompey because I had my dog with me in the van. The security guard (note: not an proper copper, or an MP or even a stoker with a gun but a security guard employed by the same people contracted to safeguard the Olympics - G4S), told me it was because terrorists had been known to pack dogs with Semtex and then explode them remotely. The fact that I was hardly likely to blow up my best mate cut no ice with this fella. So I reversed out of the gate, drove to a local transport cafe and asked the woman behind the counter if I could leave him there for 20 minutes or so.

I drove back in, the guard checked that I didn't have a dog and waved me through. At no time did he check the RIB or the two pallets of spares I had in the back of the van. In fact after that incident, I used to stop a couple of hundred yards before the gate, tell the dog to get off the seat and into the footwell and then throw a blanket over him - no problem.

In some ways, I can understand the Yanks' concerns

I remember it being reported somewhere in the recent past that the US navy had offered assistance to protect the Olympics.
The Royal Navy where apparently none too amused. It would not however surprise me if we see a "friendly" visit from an American carrier just before the Olympics starts. On a goodwill mission of course, nothing to do with the yanks ensuring they have assets in the area, because they dont trust they limeys to play ball.

I have read elsewhere that the Anti aircraft defences are likely to provided by at least one of the new Type 45 Destroyers.
These have the capability to pretty much track anything over the UK and engage something like 8 aircraft at a time.

A type 45 parked in the Thames Estuary would be able to pretty much cover the whole of London.

Combine that with RAF fighters on standby and any air major air threat could be dealt with.

Personally think the biggest risk to security will be the thousands of foreign agents mulling round London under the guise of being there as security personnel to protect their nationals from untoward behaviour.
Just imagine 1000 CIA/FBI agents milling round London armed to the teeth, a 100 or so Mossad agents, 300 russian GRU/Spetsnatz, 100 German GSG9, etc, all of whom will need watching by mi5, special branch and the normal police.

It wasn't my link, In turn I'd suggest you read the posts properly.

And to some extent yes, they are 'locked down'. Not in the defcon 4 approach I'm sure you're imagining though, in terms of vastly increased security and limited or altered flight paths.

If MI5, special branch and the normal police are watching them then who's going to be watching the Islamic terrorists or anarchists?
