Harvard economist Jeffrey Miron believes that legalizing all drugs, not just marijuana, is the only way to eliminate drug-related violence.

Miron argued during an appearance Monday on CNN, “Prohibition … hasn’t prevented kids from getting access to heroin, including very, very cheap heroin. … At the same time, we’re getting all the ancillary costs of drug prohibition, such as the violence in Mexico that spills over into the United States.”

“Some people will misuse drugs even if it’s legal,” Miron acknowledged, “but the magnitude of negative things would be vastly reduced.”

investigation by Rebecca Renner of Salon has revealed that the Center for Disease Control(CDC) had withheld evidence of dangerously high levels. An influential CDC report released in 2004 (and since cited by officials in Seattle to calm nervous parents) downplayed the role that chloramination played in the D.C. lead crisis, saying that it “might have contributed a small increase in blood lead levels.” However, according to Renner, “the results of thousands of blood tests that measured lead contamination in children were missing from the report, potentially skewing the findings and undermining public health.

A massive ice shelf anchored to the Antarctic coast by a narrow and quickly deteriorating ice bridge could break away soon, the European Space Agency warned Friday.

The Wilkins Ice Shelf — which like the rest of Antarctic’s ice sheet “was formed by thousands of years of accumulated and compacted snow” — had been stable for most of the last century before it began retreating in the 1990s, the statement said.

Even as world leaders were making arrangements to bolster military presence in Afghanistan, anti-military and anti-globalization protesters outside made their anger felt by torching two buildings. They drew swift, violent reactions from thousands of armed riot police conducting crowd control operations throughout Strasbourg, France.

Five people have been arrested in connection with a suspected plot to use explosives made from fireworks to disrupt the G20 summit.

The three men, aged 25, 19 and 16, and two women, both 20, all live in Plymouth and the surrounding area. They are political activists unaffiliated to any terrorist organisation, and were arrested at addresses in Plymouth. They are being held under terrorism legislation. The explosive devices were made from simple fireworks, police said.
