I don't believe GCHQ is involved in anything of the sort and you shouldn't either. This story simply reeks of falsehood.

Edit: Hey, that's not what I wrote...

The real enemy is drugs. If you look at all the security measures that changed, they all have to do with somebody that smuggled drugs. Why do you take your shoes off? It's not the shoe bomber, it's the girl whose story was featured on "Locked Up Abroad" who was filling her oversized shoes with hashish.

I suspect they found somebody that packed their laptop's battery compartment with drugs.
