There are millions and millions of guns in the USA. If the government were to take away our constitutional rights and ban guns, they would still be available for bad guys to get their hands on. There is absolutely no way to stop that.

I for one am glad that I have the ability to defend myself and my family with a firearm.

There's nothing you can do to be completely safe, but there are multiple options available to you to avoid or survive a confrontation. . . even in California, where guns are banned.
