Whome to blame

Last one week it has been a overwhelming news regarding the Virginia Tech Slaughter. Almost all news channels allocated most of their air time to cover this incident. Every one no matter whom it is who had contacts with the victims as well as the shooter were interviewed

Leaving all things behind if we have to see what thought would have made a normal human being do such a devastating thing ?
Killing people is not some thing a rare event. In war people kill each other. Terrorist kill common people without any kind of mercy. Of course War/Terrorism have some predefined definition for the killings.Whether they are right or Wrong that's different argument but the motive/background is known . But for this incident will a person who is a loner/mentally affected plan so well to execute a Mass Murder ?

I personally would say the parents should play a vital role in shaping a person. We can blame lots of parameters such as Gun laws,Lack of communication among Medical institutes/Police ,college authorities,etc. But none of these has a direct control on this person than those who are close to that guy. I'm not sure whether his medical records were shared with his parents. More over this country has laws of not sharing those things once a person becomes a major.
One main difference in the culture of West and of countries like India is a person is under parents control at least until he/she gets married. One gets moulded/gets to a better shape when he is surrounded by good people around him who care for him .
So a persons brought up in his younger age shapes him better. So Parents ..Pls do take care of your kids and put more effort in shaping them.
