If Russia didn't do it - who did - and why ???


.. and if If Russia did do it - how come it's such a sloppy job ???
Ineptitude, or a deliberate ploy to make the job look amateurish...?????

This is a thread not so much for jumping to hasty convenient conclusions,
but for creative immaginative conspiracy theories,
that might inadvertently get us closer to the truth.....???????????????
