I know some might say, "well what if someone trades you a gun used in a crime? And somehow the law finds out YOU have it" Beyond being in possession of a gun used in a crime, there are so many other factors needed to prove one guilty it would be almost impossible to convict someone for simply having the gun unless you were trading with someone you knew, family member, etc. Also, if it became common knowledge that gun swaps were common THAT would create serious reasonable doubt. Plus if you could show you were AT a gun swap that right there would create reasonable doubt as to whether you owned the gun when the crime was committed. I am more interested in preventing a Katrina style gun grab down the road when Obamas policies throw this nation into collapse, chaos and ruin. And royally screwing up the registry well in advance of it can only be helpful to law abiding citizens.
