Goyal et al Study: Universal Background Checks vs. “Child” Deaths

I was going to do an all-out analysis of this paper, since just from the press release I knew it had problems (cross-sectional analysis, without longitudinal; 18-21yo “children”), but this persuaded me to not waste that much time…..

So, starting with bad data, and excluding data that would invalidate their thesis, they did a cross-sectional comparison only, with no longitudinal analysis to find an effect of implementation of background check laws on in-state trends. A UC Davis study found no effect on homicide or suicide rates in the ten years after California’s passage of a universal background check law. More recently, California has seen an increase in firearms homicides……

Just another BS paper with a pre-set agenda, lacking in anything resembling science.
