It is not a case of mistaken identity. It is a greed for money and power. They might have killed so many people in this way, but, not got caught that made them bold to kill anybody at will.
It is the family and background of the innocent people who were killed by these police criminals are so strong that they could be able to fight a long battle with the entire police machinery and also the JUDICIARY. Otherwise, they would have not won the case, even after 40 years.
The police, armed forces, etc. are killing the innocent muslims in this way and plant the arms and bombs on them and make them terrorists. But, they have not got punishment, but, rewards and awards. We should be really thankful to ALMIGHTY GOD, who started showing this kind of criminals to the world to save the innocent humanbeings. Side by side, he is also punishing the killers of innocent people in his own way.
