Why did Interior Secretary Ken Salazar threaten a reporter?

The inspector general of the U.S. Department of the Interior is conducting an investigation into whether the department's Bureau of Land Management sold some 1,700 wild horses to a Colorado rancher who illegally exported them to Mexico for slaughter. According to an investigation by Politico, BLM officials would email the rancher and encourage him to buy dozens of horses, sight unseen. Advocates for the mustangs say the BLM, which is charged with protecting the horses, had to know they were being killed. Salazar threatened last week to punch a reporter from the Colorado Springs Gazette who asked him about the horses and the government's relationship with the rancher.

How does Italy plan to avoid the sort of debt crisis facing Greece?

One element of the government's plan is to go after tax cheats. Tax evasion is so pervasive in Italy that it is estimated to equal more than a third of the country's total tax revenue and 15 percent of the nation's gross domestic product. Italian authorities have set up a tip line where people can report cheats, have extended the statute of limitations and are establishing prison as a penalty for serious offenders.

This would include lane departure warning, forward collision warning, adaptive cruise control, automatic braking and electronic stability control -- technologies that could cut fatal highway accidents by more than half. Though automakers insist the changes could add thousands of dollars to the cost of a new car, NTSB member Robert Sumwalt said the technologies use cars' existing electronic systems and should not be that costly.
