most criminals that end up getting their hands on some type of gun don't do it legally
This is the most common argument I get from friends of mine who have conceal carry permits. "If criminals can get guns illegally, why shouldn't I be allowed to carry one legally to defend myself?"
The problem with any gun control laws is that a law can't control guns in the US. There are simply too many. The United States is the largest weapons manufacturer in the world. (there is some debate on which nation is the leading small arms manufacturer in the world, but the US makes the most "weapons", at any rate) The drug wars happening in Mexico right now are being fought with guns made in the US, traded illegally across the border with drugs that will be consumed in the US.
A law to complicate or prohibit gun ownership in the US would likely only affect law abiding citizens, and do nothing to hamper a criminal's ability to own a gun. And because of the 2nd amendment, a federal law against gun ownership is unlikely, meaning the individual states would have to create and enforce their own gun laws to varying degrees of success. Which means a criminal living in California, where gun laws are strict, could easily drive to Arizona to legally (but untraceable) purchase guns where gun laws are less strict, and bring them back to California, effectively making gun laws useless.
Instead of more gun laws, the systemic problem of gun accessibility needs to be addressed across the entire nation. If you want to keep guns off the streets, the manufacturers of guns would need more government regulation to ensure that weapons are tracked with some degree of certainty as they come off the assembly line and make their way to the end user's hands. Travelling gun shows need to be disbanded, as gun shows (in some states) are usually the best place to buy lots of guns with no paperwork.
We could also use technology to aid gun control, fitting all weapons with biometric security (so they'll only be usable by specific people) and GPS tracking devices.
As a gun owner myself, I'm strongly in favor of tighter gun control. I might not be in favor of an outright ban on all firearms, but there is a lot we can do to keep guns off the streets.
Now, for those of you who live in the US and think gun violence is completely out of control and the worst in the world, try living in South Africa, which experiences 3 times as many fatal gun related crimes per year as the US, mostly by criminals using guns that have never been legal for private citizens to own. This fact seems to make the point that gun laws simply don't work. Gun accessibility, both legally and illegally needs to be addressed.
