You don't need to concern yourself with guns obtained illegally. Let FBI and Law Enforcement handle it. They have done a decent job so far. Have had many seizures of guns. You have a higher chance of being killed in a car crash or getting a heart attack than being killed by a gun. And most of the guns doing the crimes were obtained legally anyways. Just because its so easy to get them. You know how easy it is to buy a gun? http://money.cnn.com/2015/06/19/news/guns-background-checks/ Here is an article from CNN. You basically have to fill out a form and you are good to go. Then they run a background check and you get approved. only 1% of all forms are denied. But gun buyers don't have to go through a background check when they make a purchase at a gun show. You can check a website for gun shows in your area. Honestly I feel like i shouldn't post this on forums, because someone will read it and see just how easy it is.
