In addition to impulse, BSF brutality and killing are supported by indian law approved by indian policy makers at highest level. How does that brutality and senseless killing reflect on so called "secular" india? It's more like indians are trying to hide their redical and fundamentalists actions behind "secular" mask.
The BSF, which has a long record of severe human rights abuses and members of India’s other security forces, are exempt from criminal prosecution unless specific approval is granted by the Indian government to undertake a prosecution in a particular case. This legally sanctioned impunity is even included in a new bill to prohibit torture under consideration in the Indian parliament. The bill, as presently drafted, will require approval from the central or a state government for a court to have jurisdiction over an offense committed by a public servant.
