According to China's Law, a Tibetan who kills less than 3 Chinese is not convicted!
In China, many Chinese people fear Tibetan very much because Tibetans easily lose temper and like fighting. They carry with them a long Tibetan knife anytime. Many Chinese people are killed by Tibetans just because of a quarrel with them. However, those Tibetan killers are not convicted and punished.
The injustice of China's law is due to the goverment's resolve to maintain the unity of the country. The impunity of Tibetan killers is just one of the many measures.
Compared to the White people who killed millions of Indians in North America and drove them to barren places, Chinais very compassionate because Chinese never launched any genocide of minorities like early Americans did to innocent indians. On the contrary, many Chinese civilians suffer from Tibetan's brutality.
Who the hell are the second class citizens in China?
