There was recently a newspaper reporter up in NorCal who was tasked with creating a 'ghost gun'. The whole idea of the exercise was to illustrate how easy it was to build a Polymer80 pistol presumably within the confines of what is legal in CA. In the process, he actually broke around a dozen laws, in several instances recording himself (and a friend) on video doing so. The idea was to illustrate the need for further restrictions, and all he really did was show how incredibly hard (and pointless, in CA) it is to even undertake the process within the confines of existing law.A lot of sensible people with no understanding of guns, etc.
The paper ultimately replaced the original story with an editorial that basically just says, "It's easy to get a gun (illegally)."
