Campus Carnage

Though the event has occur ed almost 2 weeks ago, I was tempted to express my concern for the students who lost there lives in one of the often occurring dastardly act in American universities.
Well this is not the first time such incident has occur ed in American universities, in term of damage(human life) this one will be remembered for the toll Cho had taken. People might argue that life's could be saved if after the initial shooting had occur ed at West Ambler Johnston Hall dormitory, then after 2 hours the second attack occur ed at Norris Hall engine ring building. If the authorities had warned the student after the initial incident. But the authorities replied they had no reason the believe another incident could occur and even guessed that incident to be isolated and the gunman would have left by then.
The previous incident that blotted American history with such killing in school have occur ed even way back in 1966 at University of TEXAS, then in 1999 at Columbine High School at Colorado. Though the background of the people involved in shoot outs had different background and suffered Psychological breakdown. But the key Point that is easily overlooked is the fact that it's easiest to purchase an arms in US for anyone who is above the legal age of 21. In fact the state of California has even more absurd law stating that any individual above the age of 21 can purchase to a maximum of 1 handgun per month only. Though the purchaser is subjected to background checks( recently included law). Here is the nation in the world that beliefs that owning an arm is matter of civil liberty. And there is on going debate in the country not on banning the rule to own a gun, but just to impose stricter restriction on arm posses ions. In a recently concluded survey by United Nations brought out shocking statistics that in US population of 300 million there were 200 million guns(Legalised) being circulated. And death by firearm per year stand to 0.3% per year.
What surprises me, is the fact that here are we a nation of 1 billion with more than 60% population in there prime age. Yet how many of us have seen a real gun forget owning them. Please don't include the government officials and Armed officers. Where else in US in fact more than half the population posses legalized arm. In fact there should be no doubt that such incident at universities do still keep occurring every once in a while. In fact until you have access to arms such incident can never be completely ruled from the society. No amount of metal detectors at School and University gates or stricter security can avoid such mishap occurring often.
I would like to end with small observation that its the Same country that has attacked other nations for posse sing WMD( Weapons of mass destruction), where else in there own backyard arms are being legally sold. US should realise the greatest threat they are incurring not from WMD present in Middle east countries or some Eurasian countries but from there own population by allowing them to arm themselves at their free will.
