Again and again it amazes me that people are so ignorant. The concept that making handgun ownership illegal will prevent crime is silly. The gun ban will only prevent honest citizens from owning and possessing handguns. Criminals will and most likely already are obtaining their weapons of choice through already illegal means such as theft or the black-market. These sources are not any "more" illegal due to the new law nor will criminals be more deterred from using these sources. They will however be more confident when committing crimes that the victim will be unarmed. I wouldn't be surprised to see increased violent crime rates if the proposal passes muster with the courts.
Of course the politicians, the rich, and the famous will still be able to have their permit carrying armed body guards while the general population will be left with no defense for the police who are particularly poor at stopping a crime in progress and according to the courts have no obligation to prevent a crime from occurring. They may catch the criminal after the fact but if you have been assaulted, murdered, raped, robbed, or any other myriad of things you may find this to be of little comfort.
Defend yourself, your family, your property, and most of all your rights. Even if you don't live in San Fran (Thankfully, I don't) you should be concerned. Any increase in gun control gives people like Handgun Inc and the Brady campaign another inch in the door. Your rights could be next.
