IIRC the correlation between lead exposure & violent crime rates 20 years later is fairly good: you can track it on a state by state level as each state banned lead additives in fuel at different times.
But proving any cause with a with a 20 year delay in its effect is going to be very difficult. At best it seems reasonable to believe that lead in fuel was a sizable chunk of the problem, but it’s certainly not proven beyond doubt.

It's like discovering the cause of Alzheimer's, dementia, or autism. I just find it funny, when discussing issues in comments, the depths people will go to, to frame things in black and white.
