I'm one of these strange people that thinks when an outspoken critic of Putin dies of Polonium poisoning or suddenly finds themselves imprisoned, that Putin may have had something to do with it. But that's just me. Smart people would know Putin had nothing to do with these little difficulties his opponents seem to get themselves entangled in. I imagine smart people such as yourself know that Putin is working day and night to find and arrest these assassins and go after those who have given false testimony.
