A grand jury in Mississippi Tuesday refused to indict Carolyn Bryant on charges of manslaughter for the 1955 kidnap and murder of Emmett Till due to a lack of sufficient evidence. Carolyn is the wife of Rob Bryant, who, along with his half brother J.W. Milam, was acquitted in 1955 by an all-white jury on all charges related to the murder. Rob Bryant later confessed to the killing. A friend of Till called the grand jury's decision racist, telling AP "we had overwhelming evidence, and they came back with the same decision. Some people haven't changed from 50 years ago."

The Till case leads a series of attempts by federal law enforcement authorities to settle unfinished civil rights cases. Following a probe of investigative errors, the US Justice Department re-opened the case in 2004. Last year, the FBI reported that no federal civil rights charges would be filed in the Emmett Till case, and subsequently turned over to the local Mississippi district attorney.

Charges have been brought against former interim president of Liberia Gyude Bryant for embezzling $1.3 million during his tenure from October 2003 until January 2006, according to a Liberia government statement Tuesday. The indictment was based on an audit conducted by the Economic Community of West African States (ECOWAS), which monitored the interim government after former President Charles Taylor stepped down in August 2003. Taylor is currently awaiting trial at The Hague before judges of the Special Court for Sierra Leone on crimes against humanity charges.

On Monday, current Liberian President Ellen Johnson-Sirleaf announced the government's plans to prosecute all present and former government officials involved in corruption. In December, two former finance ministers and a former minister of commerce were charged with corruption; however, the men were subsequently freed. Bryant has denied the charges against him and is expected to face trial in an intermediate court in Monrovia.

Monday's agreement is only the latest joint effort by the western states. Last year, Arizona and New Mexico formed the Southwest Climate Change Initiative, and the governors of California, Oregon and Washington issued a joint statement in 2003 calling for regional action to address global warming. Elsewhere in the country, several Northeastern states have created the Regional Greenhouse Gas Initiative, to reduce carbon dioxide emissions from power plants through a regional cap-and-trade program, and some Midwestern states signed on to the Lake Michigan Air Directors Consortium, to establish a voluntary registry for companies to report their emissions-reduction efforts.

Efforts to establish national emissions limits have gained traction in Congress since the Democrats became the majority party, with at least four major proposals emerging. President Bush opposes mandatory carbon dioxide (CO2) limits but has proposed reducing emissions through the use of alternative fuels. A coalition of businesses and environmental groups has called for federal legislation, including a cap-and-trade program, to limit emissions of CO2 and other greenhouse gases. In September, California became the first US state to restrict greenhouse gas emissions when Schwarzenegger signed a bill authorizing a state board to set emissions targets for various industries.

Oil rose on Monday as a burst of cold weather boosted heating demand in the United States and as world powers discussed tightening UN sanctions on Iran, the world's fourth-largest oil exporter.

US crude rose 26 cents to $US61.40 a barrel, just below the 2007 high of $US61.80 hit on Friday. London Brent was up 47 cents to $US61.35.

Analysts said wintry weather sweeping across the key Midwest and North-east heating markets was supporting oil's gains, and added that prices could find even more strength heading into the spring, when gasoline demand picks up.

"It is the first time this year that the large speculative funds are showing a net long position in crude oil," said Olivier Jakob, an analyst at Swiss-based Petromatrix.

Oil prices have swung between a high of $US78.40 last July, when fighting flared in Lebanon, and a 20-month low of $US49.90 in January, when an expected influx of fund money failed to materialise, disappointing oil investors.

A steady recovery in prices since late January has been supported by gradually tightening supplies - OPEC has twice cut output since November - and by concerns over a possible disruption of Iran's oil supplies.

The Supreme Court finds itself smack in the middle of a big debate over high-speed chases.

Officers in Georgia were chasing a speeding Victor Harris in 2001 when a cruiser rammed Harris' Cadillac at roughly 90 miles-per-hour, sending him into an embankment and leaving him paralyzed.

Harris sued Deputy Timothy Scott for violating his civil rights by using excessive force. Scott said he was trying to end the chase before anybody got hurt. Two lower courts sided with Harris.

This will be the first time in more than 20 years that the high court considers constitutional limits on police use of deadly force to stop fleeing suspects.

Harris' lawyer argues something more serious than a traffic violation has to occur before such force is used. Scott's attorney counters he didn't use excessive force, and that Harris was driving recklessly.
