You can find a lot of things that the internet can find a way to correlate or corroborate.
I do no doubt believe lead is dangerous at the levels it used to be in our air from billions of gallons being burnt by our automobiles but not sure if can really believe that report that it was the cause of the rise in crime at any point in time.
The next report will say it was something in the water. The next it was government experiments gone wrong. The next will say it is caused by alien activity.
Granted it surely is a possibility but just because there was lead in the air and violent crime was on the rise that that is any proof of anything.
Just as an example anyone could say something like I think it was caused when they started putting seatbelts in cars and I can show you a map that proves this fact.
Maybe it was when they started putting fluoride in the city water. Exactly anyone could say look I found the reason and can show you the correlation on paper. Certainly that makes it a fact. Maybe mercury was the reason. There used to be a lot of that stuff around back in the day.
We used to play with mercury at school. So now you know what happened to my brain cells. Today they would close the entire school over one drop of mercury. We used to play around a lot with carbide for carbide lamps at school. Oh man wet that stuff and it stunk the high heavens. I had a fire going on my desk one day from lighting a piece of wetted carbide. It turns to acetylene gas when you wet it. Neat stuff.
The FBI says crime is same today as it was in the 1960's.

Maybe the Forbes writer got it wrong and it was the 70's that the lead was causing the violent crime increase.
FBI doesn't bother to mention the lead issue if that is truly a fact of what the cause it would be so common knowledge certainly it would have been mentioned. Also it would seem it would be pretty important to stop it's use entirely don't ya think if the lead was the real cause of violent crime in the past.
Why would we not just have an outright ban on lead just like anything they stop producing because of the danger. Lead could be outlawed just as easily if the uses allowed were still posing such a threat to the population.
These are just some of the banned chemicals lead could have been added just as easily. 1 million pounds of lead is produced in the US yearly. They could limit it's use by a lot more than they have easily. Sure it is the politics and money that is keeping it around kinda doubt it is because our little toy boat engines like the stuff. Either that or they don't want the violent crime to stop completely. Lol.
