The alleged former scientist in the Sky News piece had, according to the report, accidentally contaminated himself with the agent.
And he's still alive & kicking umpteen years later.
Now, call me cynical, but if I were a state government investing in nerve agent research and production, I'd be expecting the boffins to produce something that would actually kill large quantities of enemy very quickly, not something that the same boffin can be exposed to and still yack about it in his retirement?
This alleged agent hasn't, so far as we've been told, killed anyone yet, almost a month after being used.
It cannot be, by definition, a military grade nerve agent, because so far it's failed all the requirements for such.
More concerning, perhaps, is how it got into UK, or, worse, if it was manufactured here by hostile intelligence services?
Either way, Amber Rudd's empire seems to have failed miserably, again, in protecting Britain's borders.
Why is she still in office?
