First of all, the gun laws in California ARE pretty lax. They're only slightly more restrictive that TX and AZ, which both allow for open carry without a special permit.
I'm not really sure where I stand on the issue of gun control. While I support less gun violence, I don't think gun control laws would have that effect. The problem is mainly a cultural one and that's what needs to change. more laws won't do it.
Gun violence is primarily an American problem, most of it having to do with either the aquisition, or defense, of property.
As far as the second amendment is concerned, I don't think it was written with the current interpretation in mind. Who could have imagined in the 1700s that we would have the world of today. I'm pretty sure armed robbery wasn't a big problem back then.
It was written right after the revolution, and our founding fathers wanted to make sure that the population was prepared in the event another one was needed, hence the "well regulated militia" part. Everything just mutated from there.
