So if I'm understanding the article correctly, they didn't find much in the way of specific evidence that Russia was interfering in (say) the Brexit referendum and they're blaming it on the government and security services not looking hard enough? This feels like it's getting worryingly into conspiracy theory territory, especially given the quality of the publicly available claims of Russian interference which this appears to be referencing as proof there must be something there. Edit: OK, I'm reading through the actual report now and it doesn't reassure. They literally reference the Buzzfeed "From Russia With Blood" piece which relies on the idea that Russia are so good at disguising killings that any death of a Russian-linked person - anything from a heart attack to a suicide of someone showing signs of depression who had made previous attempts - is in fact probably an assasination. This is well into conspiracy theory territory; it's basically unfalsifiable. Also, it's clear from the report that they know the UK intelligence agencies had a lot of other work on their hands regarding the terrorist threat, and this consumed a substantial amount of the resources that would previously have been dedicated to Russia, so to attribute this to the intelligence services supposedly not wanting to know about Russian interference seems itself like an attempt to interfere with the UK political process.
