An excellent article on this on CraigMurray.org.uk
Hows it going Stockhausen. Long...long time no see.
You do realise that every phone has a back door for US Intel that can be sequestered by UK GCHQ?
There's more to this Skirpal case than meets the eye. Murray links a fair bit of counter argument to bring the matter back to the centre ground. One thing is certain: Neither the UK or Russia can be trusted with their statements. Evidence should dictate, in its absence... Logic.
Who gained what from Skirpals death?
Russia: Plugged an old leak it knew of and who had likely exhausted a great deal of his intel/knowledge
UK: Worryingly, we don't know. We do know a couple of concerning things. Plausible Skirpal contributed to the Clinton dossier. He could have turned triple agent. Pushes the narrative of desire for war against Russia in an attempt to dissuade and persuade public opinion.
The last such one, is for me, what tips the balance. Until something stronger comes along as push back, its more likely the UK who have more to gain by killing him. At least for now and with the absence of evidence.
