The Florida Department of Law Enforcement faced accusations that a breathalyzer was giving inaccurate readings. So it commissioned a study. Fifteen employees consumed more than $300 worth of whiskey, mixers and Doritos, and then used the breathalyzer. Judges are considering whether the study was legitimate.

A frustrated judge in London recently exercised a little-known power: sending police into the street to rustle up jurors. The London Free Press reports lawyers in the case had questioned 130 potential jurors, and were still short. So unsuspecting pedestrians were hauled into court.

The Iowa Republican Party has certified the results of its caucuses earlier this month. Rick Santorum is 34 votes ahead, but the party will not declare a winner because there are missing results in eight precincts. Before the certification process, Mitt Romney had been declared the winner.

On the campaign trail, GOP presidential candidate Rick Santorum often discusses his opposition to abortion rights and gay marriage. That message served him well in Iowa with its large contingent of evangelical voters. Christian conservatives are also dominant in South Carolina, which votes Saturday. Santorum hopes to repeat his Iowa performance, but he's been struggling to keep pace in polls.

GOP presidential campaigns and superPACs have been spending millions of dollars on TV and radio advertising ahead of Saturday's South Carolina primary. While the negative superPAC ads air, the candidates are delivering a more positive message.

Newt Gingrich's swift rise has been fueled by one thing above all — his forceful performances in the debates. And Thursday night, Gingrich was dominant from the start when he got the first question. It was about an explosive television interview with his ex-wife Marianne.

DAVID GREENE, HOST:

As Mara just mentioned, the debate last night opened with a question about a claim made by Gingrich's ex-wife. Well, Marianne Gingrich gave her exclusive interview to ABC's "Nightline," putting the candidate's personal life in the spotlight once again. NPR's Tamara Keith has more.

TAMARA KEITH, BYLINE: The interview was incredibly hyped, in part because Marianne Gingrich has been silent so far on her ex-husband's presidential candidacy. This was her first television interview since their 1999 divorce.

Saturday is South Carolina's Republican presidential primary. It's also the second anniversary of the Supreme Court's famous Citizens United decision.

That's the case that allows corporations to explicitly support or attack specific candidates. The day will be marked with attack ads — and protests.

The Republican presidential race has covered just three states so far. And superPACs linked to candidates Mitt Romney, Newt Gingrich, Rick Santorum and Ron Paul have spent a total of $20 million. They're feeding voters a heavy diet of negativity.

The last Republican presidential debate before Saturday's South Carolina primary was expected to be lively. It didn't disappoint.

It was clear, even before the four remaining candidates met on the stage in Charleston, SC, that at least three of them would face some fairly high-stakes moments that could change the course of the contest. The question going into the debate was would they be able to master those moments?

When a pro-democracy movement took to the streets of Morocco last February, King Mohammed VI, who's been on the throne for more than decade, responded swiftly.

Within weeks, the king proposed a new constitution and snap elections. The Moroccan example of reforms without violence was hailed by some as a model.

Millions of homeowners are finding out that their property taxes are either holding steady or climbing, even as their house may be worth much less. There may not be much they can do about it.

In Ohio, Cuyahoga County's fiscal officer, Wade Steen, has been taking many calls from unhappy homeowners. He says they most often live in a community where voters passed a recent levy. That's a property tax measure that boosts funding for things such as schools and libraries.

The U.S. Food and Drug Administration has a gathered a group of scientists and other experts to study flavored melt-in-your-mouth tobacco products.

The panel, meeting this week, will hear from two camps of stop-smoking advocates: those who worry that dissolvables are a gateway to smoking and others who say they help people kick the habit.

Gregory Conley, a 24-year-old law student at Rutgers University, pops a dissolvable during class or while he's studying.

If you listen to commercial radio, this is not news: Katy Perry had a huge year. She went No.1 five times. She was the most played artist on the radio. But the record industry is so weird, it's hard to know whether this kind of success translates into huge amounts of money.

So we asked.

I walked over to Katy Perry's record label. She's on Capital, which is under EMI. I met Greg Thompson, executive vice president of marketing and promotion at EMI.

"Did you guys end up in the black?" I asked.

Whenever the late New York Times caricaturist Al Hirschfeld sketched Carol Channing — whether picturing her as an indomitable Dolly Levi, swathed in feathers and sequins, or as carbon-crazed Lorelei Lee, eyes sparkling like the diamonds that were that splendid creature's best friends — he always made her appear a creature composed entirely of lipstick, mascara and hairspray.
