At first glance I thought this post was a bit facetious, but after thinking about it and reviewing some research around people manufacturing the bullets and how it affects them and understanding that detonating them in confined spaces probably is just as if not more problematic. And if you have a job that requires you to do it often, say a cop, does that create even more of an effect? Lead exposure causes a loss of impulse control as well as intelligence effects. Could that be one reason why cops are so much more violent than the average person? I’d love to see a study on lead content of blood in cops, especially ones who murder people they capture, but unfortunately, the NRA is probably too powerful to allow that to happen. And conservatives hate masks, so I doubt it would be easy to convince cops to wear them while practicing.
Interviews by an FTE manager and reasonable complaint management and resolution like every other customer facing job would be a start.
