Just days after a man wielding two alleged ghost guns shot seven people, five fatally, Philadelphia leaders sued two companies that make untraceable weapons.
According to the city's lawsuit, "So-called 'ghost guns' -- home-assembled, unserialized, and untraceable firearms that are sold and purchased without regard to firearm regulations -- have become the weapon of choice for those seeking to evade firearm laws. Unsurprisingly, the number of ghost guns recovered at crime scenes has skyrocketed in recent years."
