Now, simply speaking as a Devil's Advocate...
This proposal will not deny anyone the "right to bear arms."
What it will do is limit the amount and kind of weapons labeled as "assault weapons" that are being made to the general public. It is in no way denying anyone the right to purchase a firearm.
And just what do you consider an "assault weapon"? you would be suprised at just what is considered an "assault weapon". According to some, an old black powder cap and ball revolver could be an "assault" weapon because you can shoot it 6 times before reloading. I have a nice little 22 cal carbine that holds 10 shots and is considered an "assault weapon" by many. Almost any semi auto 3 shot shotgun is considered "assault weapon."
A piece here a piece there and the next thing you know all guns of any type are banned. That is what they want and they will accept nothing less. Once you are unarmed you are helpless against the criminal. Show me a country in this world with guns banned where the criminal does not have weapons.
Personally i would feel quite safe breaking into someones house in Canada and England and in any country that banns guns from private citizens. A little rape here, a little robbery there, maybe a murder now and then. The only thing the police can do for you is bring a blanket to cover your dead body under those circumstances.
Some great examples of gun banns around the world, Nazi Germany, Communest China/Russia, any dictatorship in the world just loves gun bans on private citizens.
I agree there should be gun controls. There are just to many people in this world that should not be allowed firearms, but we already have gun laws in every state and at all levels. Half of which are not enforced with any regularity, enforce those with great vigor and make the penalities strong. Quit giving criminals life for murder and then letting them out in 15 years.
