Well, problem is that it's more of a slow time release thing with lead in the brain. We're still dealing with the fallout from lead in paint and water pipes that were banned decades ago but it takes a while for the lead to leech into the brain, so they don't tend to get dumber and more aggressive until later in life. So the people touching lead ammo will probably get worse as they age. Of course there could already be significant overlap with the lead paint and lead ammo people. In which case they're probably just fucked.

So it might help, but it will take a lot longer than we'd like.

We are still seeing a net decrease in crime from the ban of lead paint and lead in gas.

It doesnt just fall off within 6-12 months of stopping exposure. The decline in negative issues from lead exposure can take generations
