it is unfortunate that our bright students die in US.we believe that the gun culture in US is responsible for that. The arms are easily available to criminals there and we believe that the students are murdered for some petty reasons.Hope mr Bush takes steps to prevent those kind of killings by bringing a law for minimising Arms usage,But US is run by arms dealers and big financiers.US it self is an international arms dealer.So it won's happen.WE pray GOD to save our children studying there...
