Gun Control & RKBA

This is how I would answer.
"Some people would also say that dinosaurs and humans co existed before the great flood, it doesn't mean they should be able to make policy. First, criminals and terrorists don't go to licensed gun stores or gun shows. We know that on studies like the Wright and Rossi studies decades ago. That being the case, background checks won't prevent criminals and terrorists from getting guns because they them. The two Quran Salifasts in California got them through a straw purchase, in violation of federal law. The buyer transferred the guns to the terrorists in violation of California's UBC. Why would they if they can get machine guns on the black market just like Quran thumpers did in Paris and other parts of Europe? It doesn't matter where you are on this planet, if you can get heroin, coke, or pot, you can get a gun. Heroin, cocaine, and other drugs have been illegal for over a century. Pot has been illegal since the FDR administration. Last year, there were more heroin deaths than homicides. These people who kill each other over market share won't be able to get guns? How do we have a serious conversation with people with the critical thinking skills of young earth creationists."
