Legal gun owners are not the problem. Why should they have to pay for the behavior of criminals? If an auto manufacturer has a defect that kills owners, it's the defect that's responsible, and the manufacturer is liable. If a gun is used to kill someone, it's because of the person using the gun.With guns, it's defective people that are the problem, not defective guns. We could fix part of that by putting gun safety education into the public schools. The rest of it needs some serious research. But almost all of the research is obsessively focused on 'proving' that guns are the problem.
The mass shooters are legal owners until they pull the trigger. Responsible ownership is a myth. Until the pull.they are just like you. Having weapons available like we do is asking for trouble and we are getting it.
