This murder has been discussed to death. It was plain enough from the beginning that Litvinenko was killed for defecting. I don't know why the story keeps resurfacing.
the murders were not carried out against civilians. an individual playing playing tinker, tailor, soldier can no longer be considered a "civilian" IMHO. Death however tragic is a soldiers death. So yes those innocent kids in Irak, Lybia, Syria, Afghanistan, (you know the ones often referred to as "fun sized terrorists" by cowardly US drone operators) do have a higher value than some soldier who knows what they got themselves into.
The inquiry says - 'Putin probably approved...'
'Probably'? Come back with facts and proofs.
The amount of whataboutism [1] in this whole thread is embarassing.
