Lobsang Sangay's crime is not limited to encouraging the Tibetans to self-immolate or siphoning the money, but he also had molested many women. He thinks he is the leader of the Tibetan community so he can get away with it easily.
This is just how the Tibetans work. The more power one has, the more hanky-panky thing they are able to do. Some Tibetan politicians or even monks like to use the Dalai Lama's name when they are confronted by the authority, hoping that they can get away with things.
Lobsang Sangay had molested not 1 but a few women. Because he is the leader in the Tibetan community, no one dares to confront him. Many women did not want to re-live the bad experience so they choose to remain in silent. If Lobsang Sangay does not change his attitude and behaviour, one day he will end up like Dagri Rinpoche.
