Well, one fact stands strong: Denmark, Sweden and Germany have stoped investigating. If they had found any shred of proof of Russia's involvement they would have splashed it all over the MSMedia for months on end.... Clearly they didn't .... so why the deafening silence?
There must be something terribly uncomfortable about what they did find. Especially in regards to the sheer astronomical collateral damage it inflicted on all gas dependent economies worldwide. One would have expected an unrelentless commitment to find the culprits. The fact they aren't is simply shocking and doesn't inspire much trust.
