Examples of elected governments not protecting or even attacking the rights of their own citizens are
(i) Ethnic massacre of Albanians in Kosovo.
(ii) Policy of apartheid in South Africa.
(iii) Rule of Augusto Pinochet in Chile.
(iv) Rule of Robert Mugabe in Zimbabwe.
These rulers wanted to hold power and keep the people under their control so that they would not oppose them and they could rule without problems.
