Guys, you do not understand how Russia works. I live here. Trust me, it was most probably russians because of the style. EVERYTHING in Russia is affected by the corruption. And here we see a messy and unsuccessful attempt to kill someone with a wrong mean at the wrong time.
No need to look for deep state. The order of murder was given a long time ago. All the financing was stolen the job was not done. The same cycle was repeated a couple times with heavy stealing all the while. Finally from all the millions issued on the murder a couple thousand bucks fell in the hands of the actual hitman. Unprofessional unprepared with insufficient information he tried to get his hands on weapon of any kind. It is hard to get a gun and transfer it abroad. But it is possible to find a can of some deadly substance on the black market which was stolen from some secret vault by some military officer who is also stealing on a daily basis.
This is normal here. Everything that is done poorly is most probably done by the government.
There is corruption everywhere in the world, but there is no proof that either the Russian government or Russians attempted to poison turncoat low life, Sergei Skripal. You living in Russia - true or untrue - doesn't diminish the call for a proper and independent investigation. You living in Russia also don't remove the possibility that you're a turncoat yourself. It is after all no secret that there are scumbag Russians that are more than willing to work against Mother Russia for crumbs from the table of Western intelligence services. In addition, it is very easy to use a VPN service to register at forums and pretend to live there. I will pass the details onto the SVR and FSB for verification.
