I would hesitate to attribute the decline to Big Brother when there is already a widely accepted hypothesis explaining both the increase and the decline. tl;dr: Lead exposure has been shown to stunt intellectual development and increase aggression. With the 50s came the personal automobile, powered by leaded gasoline. Crime rose as that generation grew to adulthood. In the 70s use of lead in gasoline declined due to the clean air act. As that generation grew to adulthood crime rates fell. In the 90s the use of lead was banned. That generation is reaching adulthood now. Lead polution peaked in 1973, violent crime peaked in 1993. https://en.wikipedia.org/wiki/Lead-crime_hypothesis https://en.wikipedia.org/wiki/Lead-crime_hypothesis https://en.wikipedia.org/wiki/Tetraethyllead https://en.wikipedia.org/wiki/Tetraethyllead https://www.motherjones.com/environment/2016/02/lead-exposure-gasoline-crime-increase-children-health/ https://www.motherjones.com/environment/2016/02/lead-exposur...
