After emotional appeals from parents on both sides of the case, Dharun Ravi was this afternoon sentenced to 30 days in jail and three years of probation for bias intimidation and invasion of privacy when he used a webcam to spy on his gay roommate at Rutgers University in September 2010.

Without commenting on the merits of the case, the Supreme Court this morning let stand a $675,000 jury verdict against a 25-year-old Boston University student who downloaded 30 songs nearly a decade ago and then shared them with others on a peer-to-peer network.

The court denied Joel Tenenbaum's "write of certiorari," which means his appeal of a lower court's ruling and the judgment were turned down.

Who dumped the dope?

That's the question of the day along the coast of Southern California as authorities try to figure out how four tons of marijuana — more than 150 bales — got into the Pacific Ocean near Orange County's Dana Point Harbor. They were found this weekend about 15 miles out to sea.

After its much-ballyhooed initial public offering on Friday ended with the stock's price just about where it started, Facebook ended sharply lower today.

Just after the start of trading, the social media giant's shares were trading around $33, down 13 percent about $5 from Friday's close. At close, it ended 11 percent lower at $34.03.

Good morning.

Our early headlines:

-- Dozens Killed By Suicide Bomber In Yemen.

-- Pakistan Threatens To Overshadow NATO Summit.

-- Eclipse Of The Sun: Did You Fall Into The Ring Of Fire's Path?

As President Obama and other NATO leaders wrap up a two-day summit today in Chicago, the ongoing dispute with Pakistan over reopening supply routes from that country into Afghanistan threatens to "put a crimp in the Obama administration's efforts to lay out a clear strategy for winding down the war in Afghanistan," NPR's Jackie Northam tells our Newscast desk.

It's been another deadly day in Yemen:

According to the BBC: "At least 63 people have been killed in a suicide bomb attack during a rehearsal for a military parade in the Yemeni capital, Sanaa, officials say. The assailant, who was reportedly wearing an army uniform, blew himself up among a group of soldiers at al-Sabin Square, near the presidential palace."

"That's got to be the prettiest thing I've ever seen," Brent Veltri of Salida, Colo., told The Associated Press, when asked about the eclipse of the sun that was visible across the western U.S. on Sunday afternoon and in much of Asia earlier today.

The celestial show attracted quite a crowd. According to the AP:

With National Dog Bite Prevention Week set to start Saturday, the Insurance Information Institute wants Americans to know that:

-- Insurers paid $479 million in home owner insurance claims involving dog bites last year, up 16.1 percent from the year before.

-- The number of such claims rose 3.3 percent, to 16,292.

-- The average cost per claim grew by 12.3 percent from the year before, to $29,296.

Update at 1:17 p.m. ET. Support Afghanistan In 'Different Way':

During their meeting in the White House, President Francois Hollande, the new socialist leader of France, said he told President Obama that he was committed to withdrawing French troops from Afghanistan by the end of the year.

But, the AP reports, Hollande said he was committed to supporting Afghanistan in a "different way."

This was Obama's first meeting with Hollande.

The two leaders also said they wanted Greece to remain a part the European monetary union.

Before President Obama welcomes world leaders to Camp David and Chicago, new French President Francoise Hollande is expected to say he wants his nation's 3,300 troops home from Afghanistan by year's end. That could upset other NATO nations.

Among the key things to know about what's in the hundreds of pages of evidence and other materials related to the Feb. 26 shooting death of Florida teenager Trayvon Martin, which were released Thursday:

Facebook's much-publicized first sale of stock to the public started with a bang late this morning as the price per share jumped. But though the volume of shares sold was a record for an initial public offering, the stock's price gave up its gains as the day continued.

By the end of trading in the U.S., Facebook had settled right at the $38 initial offering price that had been set before shares went on sale.

President Obama has said "I don't bluff," when it comes to opposing any effort by Iran to develop nuclear weapons (which that nation says it is not trying to do). And, he told The Atlantic's Jeffrey Goldberg in March, "all options are on the table."
