The media seems to leaking details about the presumably secret MI5 report about extra physical security measures for the Palace of Westminster Parliament buildings e.g. thr BBC reports that:
"The MI5 report will be presented to the House of Commons Commission, which oversees security for Parliament.
The security service urges the replacement of large concrete blocks sited around Parliament.
Officials are said to be horrified the blocks could become "lethal projectiles" if a suicide bomber drove a car loaded with explosives into them, according to BBC political correspondent Gary O'Donoghue.
There are also said to be concerns Big Ben could topple onto the Commons chamber in the event of a terror attack."
So what happens to the glass fronted Portcullis House and the Westminster Tube station, if a truck bomb powerful enough to topple Clock Tower which houses Big Ben , is detonated in Bridge Street ? c.f. the Map of the Parliamentary Estate (.pdf)
Or is some sort of aeriel attack scenario envisaged instead ?
Could someone explain how an explosion powerful enough to launch the concrete blocks as "lethal projectiles" would not also be powerful enough to do the same to the stionework , masonry and glass of the Palace of Westminster itself ? What about the metal debris from a bomb carrying vehicle and any deliberate shrapnel contained in the device itself ?
Why are the concrete blocks seen as a problem ? They are presumbaly designed to hinder the physical approach of vehicles, although how successful they would be in stopping a large vehicle with a lot of momentum is questionable.
Was the design of this concrete block barrier actually tested before it was so hastily installed ?
The only "upgrade" that seems to have happened after the blocks were installed is that they have been "camouflaged" by painting them black. There do not seem to be any foundation anchors or netting or sandbags or water containers etc. to actually absorb or dissipate blast damage.
Is the plan to now insttall an ugly soild steel blast wall ?
It does not matter if the Palace of Westminster is destroyed or all the politicians and journalists inside it are killed - the terrorists will not have won - we will simply elect new politicians and rebuild.
