AP Photo/Jae C. Hong, File “Ghost gun” is a term designed to scare the hell out of the uninitiated. For better or worse, though, it worked. People are terrified about the idea of untraceable firearms, never realizing how many guns with serial numbers can’t really be traced, either. Now, people are working very hard to ban these untraceable “ghost guns.” One state recently passed a law doing just that. However, gun rights advocates haven’t fallen for the fearmongering nonsense. They’ve filed suit to overturn the law. A Delaware-based gun rights group is suing the state of Nevada over its ban on ghost guns that was recently enacted.
