Who would be in charge disarming everyone?
Could you guarantee that all criminals, everywhere, would totally disarmed?
What guarantee would there be that governments wouldn't use the opportunity to move to tyrannical positions against their own people?
How do you explain the low murder rate in Switzerland, where it's mandatory for people to be armed (this has allowed them to maintain their neutrality)?
Do laws have any impact on those who are not willing to obey them?
Do people have a right to defend their lives, propterty, and family? If so, why would it be appropriate to dictate how?
The arguments you present are old ones...firearms are used over two million times a year in self defense. Should those people have not used them and allowed themselves to be mugged or killed?
Anyone who leaves a gun accessible to children should be locked up. I have two young children (4 & 6), I also own two rifles, both of which are locked in a safe, with trigger locks on them, the keys to which are carefully hidden.
They would have to come and take my guns, should they be outlawed.
"Laws that forbid the carrying of arms. . . disarm only those who are neither inclined nor determined to commit crimes. . . Such laws make things worse for the assaulted and better for the assailants; they serve rather to encourage than to prevent homicides, for an unarmed man may be attacked with greater confidence than an armed man." -- Jefferson`s "Commonplace Book," 1774-1776, quoting from On Crimes and Punishment, by criminologist Cesare Beccaria, 1764
"Before a standing army can rule, the people must be disarmed; as they are in almost every kingdom in Europe. The supreme power in America cannot enforce unjust laws by the sword; because the whole body of the people are armed, and constitute a force superior to any band of regular troops that can be, on any pretence, raised in the United States. A military force, at the command of Congress, can execute no laws, but such as the people perceive to be just and constitutional; for they will possess the power." -- An Examination of The Leading Principles of the Federal Constitution, Philadelphia, 1787
