It seems people have lost faith in many of govt agencies and think most of them being headed by money driven jokers...though it is true to large extent, we ourselves are jokers who'll pay under the table to get anything done. We do not want system to work properly because the loopholes allow us to get things done with money whenever required and as per our convenience...remember getting a driving license sitting at home by paying a tout. So, to clean the system, we must first become obedient citizens and support all law abiding citizens who are facing atrocities from these govt agencies and use RTI as tool against bribery...this must happen if we want India to progress. For this case, I believe CBI has done good job and at least have a real motive revealed. I do not believe any parents will kill or be part of killing their only child becoz of illicit relations or anything like that. Talwars are educated, intelligent and respected people in society and know that murder does not take them anywhere. And definitely killing their only child for what on this earth???
