I have long said that this is one of Putin's gravest errors. However, allegations of torture remain just that. There are cases of proven bad-policing in Russia, but no major nation on Earth doesn't have it. It's not an excuse, but we can't simply conclude that all Russian law-enforcement is sadistic.
The infringement of the most basic right to freely worship in Russia does indeed warrant “grave concern.” The raids of Jehovah’s Witness homes — which are available online to watch — are reminiscent of what Putin suggests is a bygone era and are a de facto example of the Kremlin’s repressive regime. It is especially harrowing that Jehovah’s Witnesses, a denomination known for their refusal to engage in war and their devotion to non-violence, are being sadistically tortured under the expectation that they will not retaliate.

I've studied many publications of the Jehovah’s Witnesses and read about the prophecies of their top leaders that have turned out to be false. The Jehovah’s Witnesses leadership has simply changed the times or simply poured the prophecies down the memory hole as if they were never made. I have serious theological issues with their interpretation of Jesus's teachings too. Never the less, the way to counter them is not via persecution but intellectual, open debate. The same holds for the Mormons and Scientologists and all the rest. Freedom of religion is important. Yes, Russia has a moral right not to allow religions promoting violence and human sacrifices and such, but the Jehovah’s Witnesses are the farthest thing from that.
