The reinternment of political prisoners freed after amnesty, and the detention of others for the same political crimes for which amnesty was given, constitutes violation of basic human rights. Governments having held political prisoners against public protest for a long time may release them or give a general or qualified amnesty to abate the protest, and then shortly afterwards start making secret arrests. Alternatively, they may release prisoners, but keep them constantly under police surveillance and restrict them to a certain area far from their home, so that it is very difficult for them to find work.
