Kids Are Killing a Lot Fewer Cops These Days

Let’s end the day with some good news. As you all know, violent crime began falling after leaded gasoline began its phaseout in the mid-70s. And because lead affects the brain development of infants and toddlers, the fall in crime began with the youngest kids. In the mid-80s, only young children were showing signs of reduced violence. By the mid-90s, everyone under 20 started to show effects. By the mid-aughts everyone under 30 was starting to get less violent.

In other words, the first cohort to benefit from reduced lead was juveniles. Kids born in the late-70s showed only small improvements because lead had been only slightly reduced during their childhood. Kids born in the late-80s showed more improvement because ambient lead had decreased quite a bit during their childhood. Kids born in the late-90s showed yet more improvement, etc.

Rick Nevin has sent me a new chart that shows this vividly:

In the early 90s, young people between the age of 18-24 killed an average of 33 police officers per year. By 2015 that was down to 4. For juveniles under the age of 18, the number was zero.

Kids just aren’t as dangerous as they used to be, and that’s likely to be a permanent change. As time passes, this will affect older and older generations as the cohort born in the late-80s (when most lead was gone) grows up. How much better does news get?

DEMOCRACY DOES NOT EXIST...

without free and fair elections, a vigorous free press, and engaged citizens to reclaim power from those who abuse it.

In this election year unlike any other—against a backdrop of a pandemic, an economic crisis, racial reckoning, and so much daily crazy—Mother Jones' journalism is driven by one simple question: Will America will move closer to, or further from, justice and equity in the years to come?
