I can't add to what Roper, Alex, Ribka, et al have said. MY guns have cost no one else anything; in fact, they have saved myself & others from harm. Fact is, you can't legislate or implement via purchase (read "tax") ethics or morality. Until such time people realize that perpetrators of heinous crimes, no matter what mechanism of destruction they choose to employ and do not conform to ANY laws including God's laws, such atrocities will continue. The root cause is NOT firearms owned & used by honest, responsible, law-abiding citizens. Thus, regulating/punishing honest gun owners does NOTHING to those who would perpetrate acts of violence. Such actions would, however make it much less-risky for said vermin to prey more-widely on their chosen victims. Boot, I sincerely commend you for your passion to heal/improve the health of others. I will also continue to defend my Second Amendment rights. Peace and light . . .
