What do you say about the 4 year drama that Congress did with Kasab? They freaking gave him a lawyer after hundreds of witnesses were there including CST CCTV cameras that caught him butchering innocent fellow Indians.
It was not the congress that gave him a lawyer, it is the law of the land. Everybody is entitled to legal representation and a free and fair trial. The congress has no say in that. As for the case taking four years, you can blame the judicial system for that.
