*BUMP*! . . . This is good evidence Putin ordered the hit.
I.E. the moment the guy died died FR was immediately rushed by posters who claimed that Putin had ordered the hit. Their evidence ....none, just that they were 'sure' it was Putin.
A few days later a new wave came up that said that it could have been an oligarch (who obviously had a bone to pick with Russia, had the financial resources being a multi-billionaire, and was one of the last people that had contact with the ex-spy). There was also no evidence here, just some speculation.
Then a reverse backlash occured, with the 'Putin did it' camp saying that no other person could have done it apart from Putin (my favorite comment being that Putin did it because he was KGB). Once again no evidence.
Then it came out that the guy had converted to Islam (a point that the 'Putin did it' camp VEHEMENTLY denied until the guy was actually buried in an Islamic ceremony. Some of the 'Putin did it' camp actually went as far as saying that the Islamic conversion story was a psyops attempt by the Kremlin).
Hence you can see why I am very sceptical ....with both camps. It appears that FR is divided into two groups in regards to this case. One group believes Putin is the devil (more or less) and is responsible for this, and nothing can dissuade them from that. The other group believes that Putin had nothing to gain from this and it must have been due to some other actor or event (eg an oligarch, or the guy actually poisoning himself while trying to deliver the stuff to sell to some group trying to activate suit-case nukes).
Hence when you say that you have 'good evidence' that Putin did it I am immediately curious and would love to see this evidence. Hopefully it is coherent and not another dose of regurgitated speculation.

Like hell it is. Russians are nothing if not EFFICIENT killers. Killing someone with a 10 million dollar weapons is more in line with the old US style of hitting a few empty tents with Tomahawk Cruise Missiles.
If Russia was going to kill someone with radiation, Cesium-137 would be a lot cheaper and maybe just as effective.
