Soylent Green Is People said:Irvine Commuter - perhaps those at the Bataclan may disagree with you. No matter the weapon of choice - gun, truck, bomb, knife, poison, there are plenty of mass killings that are not gun related. Everyone loves the stat that Australia banned guns and killings were reduced... a good thing... but they fail to mention that the crime rate soared thereafter - a bad, and ongoing problem. Oh... and criminals still have access to guns.
Bombs are illegal. Knives are harmful but I much rather a crazy person have knife than a gun. Not to mention the the cost/benefit analysis of a knife versus a military assault type weapon.
And the Australia thing is categorically false. There is very little evidence the gun ownership means lower crime. There is a lot of evidence that gun control work to reduce gun violence both domestically and overseas.
