whether its the case of haren pandya or its the case of hyderabad blasts or bangalore blasts almost 70% of the masterminds are criminals who have been let off due to the lack of evidence.
is it not mere stupidity to question the reason for pota in the light of the above facts. using pota people can be taken into preventive custody which would have been of great help if used in case of ahmedabad after bangalore blasts as the investigation shows the bombs exploded just after 1 or 2 hrs after planting them
