 ::: I just streched your own logic, no, the home minister need not have a role in all the decisions taken by the police officers. You mean to say a police officer decided to slap a beggar and home minister has a role in it? It would be a stupid argument. The encounter is fake so if Amit Shah had a role he would be behind bars now. What is being investigated is whether he was really involved in it or not. When you say that he had a role in fake encounter, you are passing a judgement that he was involved in orchestrating the encounter, which is not known. Whether the home minister was involved or had a role in the decision of police to kill Sohrabuddin Sheikh is something that is being investigated, it means that it is alleged that Shah had a role in the decision of police to kill Sohrabuddin Sheikh. Also what you are doing by saying the home minister has a role in any decision involving senior police officers"" (which is what I'm saying) is passing a judgement which is not only OR but also imposing your own POV   -  "
