Supporters say the measure tackles the problem before a downloadable file becomes an untraceable weapon. Everytown for Gun Safety says recoveries of 3D-printed crime guns across 20 cities have risen nearly 1,000% over the past five years, and argues that cheaper, more capable printers are already being used in illegal ghost gun operations.

Ooooh, that’s two large red flags for me (disregarding the litany of red flags the concept in general has). Every town being involved makes me question the data on its face, given the number of times I saw gang violence near a school out of school hours listed as a school shooting in their database, as does a large percentage increase with no hard numbers. If they recovered 1 gun last year and 11 this year, that’s a 1000% increase, but the percentage sounds so much worse than the real number.
