Hi Simon,
I think the found explosive weapons could be unusable, possessed by a non-JW (e.g., an "unbelieving" relative) - or planted. It's surely not impossible that a JW possessed them, but the probability is too small.
Anyway, Russian media already use this "news" in their "The Eternal Jewhovist"-style hate propaganda and portray Witnesses as potential terrorists - very alarming move that can result in violence from misinformed or malicious law enforcement and state security forces.
drearyweather Can you list down all the legally registered religious groups that have been declared as "extremists"? Not just persecuted, but legally declared as "extremists"? Please include only religions, not nationalist or fundamentalist groups.
Good question. Neither Mormons nor Pentecostals nor Hare Krishna (backed by Indian Government) nor even Scientologists are banned in Russia. Many religious groups (incl. dissenting Orthodox Christians and Baptists) are suppressed but it's not a "crime" to be their adherent.
