I wonder what is the purpose of the photo? Is it an act of calm defiance to signal to the Russian powers that the Watchtower cannot be stopped? Or as photographic evidence to others in the organization that the preaching work is being carried out? I have never before seen a photo like this - and am left thinking it may not necessarily be sanctioned by the GB - it potentially could put the organization at greater risk in Russia. It is also naive for individual Witnesses to cover their faces when Russia is known for its blanket oppression and has less interest in targeting specific individuals than in closing down groups.
This could backfire against the organization in crazy ways if it is construed an act of defiance.
