The Leaden Echo and The Golden Echo - Early Childhood Lead Exposure and Criminal Activity Later In Life

...Although crime did fall dramatically in New York during Giuliani's tenure, a broad range of scientific research has emerged in recent years to show that the mayor deserves only a fraction of the credit that he claims. The most compelling information has come from an economist in Fairfax who has argued in a series of little-noticed papers that the "New York miracle" was caused by local and federal efforts decades earlier to reduce lead poisoning. The theory offered by the economist, Rick Nevin, is that lead poisoning accounts for much of the variation in violent crime in the United States. It offers a unifying new neurochemical theory for fluctuations in the crime rate, and it is based on studies linking children's exposure to lead with violent behavior later in their lives. What makes Nevin's work persuasive is that he has shown an identical, decades-long association between lead poisoning and crime rates in nine countries...

The Number

Whatever one's opinion of its possible limitations, the 2006 Iraq mortality survey produced epidemiological evidence that coalition forces have failed to protect Iraqi civilians... If, for the sake of argument, the study is wrong and the number of Iraqi deaths is less than half the infamous figure, is it acceptable that "only" 300,000 have died? Last November, with no explanation, the Iraqi Ministry of Health suddenly began citing 150,000 dead, five times its previous estimate. Is that amount of death acceptable? In January, the United Nations reported that more than 34,000 Iraqis were killed violently in the last year alone. Is that acceptable?
Regarding The Number, the result of what one of the study's authors calls an episode more deadly than the Rwandan genocide... [more within]

The decline of rape aka feel free to walk on my lawn

The three-decade decline in teenage and young-adult rape accompanies huge drops in all crimes -- murder, assault, drug abuse and property -- committed by youth... Women's rapidly rising status and economic independence in the larger society fostered new attitudes and laws that rejected violence against women. That younger people growing up in this environment of greater gender equality should show the biggest decreases in rape, while older generations lag behind, is consistent with this explanation... Over the last 30 years, rape arrest rates have fallen by 80% among Californians under age 15, much larger than the 25% drop among residents age 40 and older.

So, kids today are different.

Iraqi Death Rate May Top Our Civil War: Deaths in Iraq: How Many, and Why It Matters

...Would it surprise you to learn that if the Johns Hopkins estimates of 400,000 to 800,000 deaths are correct -- and many experts in the survey field seem to suggest they probably are -- that the supposedly not-yet-civil-war in Iraq has already cost more lives, per capita, than our own Civil War (one in 40 of all Iraqis alive in 2003) ? And that these losses are comparable to what some European nations suffered in World War II ? You'd never know it from mainstream press coverage in the U.S. "Everybody knows the boat is leaking, everybody knows the captain lied," Leonard Cohen once sang. The question the new study raises: How many will go down with the ship, and will the press finally hold the captain fully accountable ?
