The murder by Adam Lanza with a .223-caliber assault rifle and at least two other guns of 27 innocent people today, including 20 children between the ages of 5-10, in Newtown, Connecticut, USA is clear evidence that it reform in American gun laws is long overdue. It is absolutely ludicrous that people can obtain firearms so easily in America and leads to horrors like this. Please sign this petition to demand that gun laws in the USA are significantly tightened. How many more people have to lose their lives in order to uphold this 'constitutional right' of Americans to bear arms.
