The killing of 26 in Connecticut was an act of a person needing mental help! How did he find this weapon? Because this weapon did not find him. Guns are always to blame, not the person pulling the trigger.
Let's look at the other things to blame. I did a little research and found that every day in the USA, 128 people are killed by an automobile — let's blame the car, not the drivers. Around 3,000 killed in 9/11 attacks — let's blame the airplanes, not the terrorists who committed the crime. Let's ban knives, because my research found that in the USA, an average of 68 people die of stabbings daily. Let's ban all men, because it's their fault that 3,500 infants are killed daily from abortions in the USA — not the lawmakers who make all the rules.
It's easy to blame the materials — not the individuals who commit the crimes! Face it: If all weapons were on earth without people, would this happen?
