The Secret Service prostitution scandal in Cartagena, Colombia has dominated U.S. headlines and attracted responses from a number of high-profile Americans including the president himself. Obama said last weekend: "If it turns out that some of the allegations made in the press are confirmed, then of course I'll be angry." But what do Colombians think of the whole scandal? Miriam Wells is managing editor with Colombia Reports in Colombia.

Yesterday, the House Judiciary immigration subcommittee held a meeting called "Holiday on ICE." Contrary to how it might sound, it had nothing to do with dancing elves or figure skating. In this case, ICE refers to Immigration and Customs Enforcement, the federal law enforcement agency under the department of Homeland Security that enforces immigration laws. Here to tell us about detention, past, present and future, is Doris Meissner, who served as Commissioner of the INS under President Clinton and Acting Commissioner under President Reagan. She is currently director of the U.S. Immigration Policy Program at the Migration Policy Institute.

The crisis in Somalia continues, with drought and famine plaguing the country and millions of refugees fighting for survival. The U.S. has approved $565 million in humanitarian aid so far this year. But our involvement in Somalia is does not stop there. According to an article in The New York Times yesterday, the U.S. has quietly been stepping up clandestine operations inside Somalia, training Somali intelligence operatives, interrogating suspects, and sending $45 million in arms to African soldiers and private security companies, to fight against the Shabaab, an al-Qaida aligned militant group.

How did U.S. forces coordinate Osama Bin Laden's death? Takeaway Washington correspondent Todd Zwillich explains the nuts and bolts of how this happened, and reports on the reactions in Washington, D.C.

Following the news of Osama Bin Laden's death, Celeste Headlee is reporting live from Ground Zero this morning, where family of 9/11 victims and others have gathered to celebrate. Jared Ring, a New York City paramedic supervisor who left Eastern Long Island at 1:30 am to come to Ground Zero, speaks with us. Also, Miranda Nichols, a student from St. Johns University.

Are the companies who deny services to WikiLeaks, and the hackers who attack those sites in retaliation, starting a cyber war, and if so, do both sides have a digital ax to grind? 

We’ve learned a lot more about Julian Assange since he began publishing tens of thousands of classified documents on WikiLeaks last Sunday. Some believe he’s a hero. Others call him dangerous. Neither the U.S. nor Britain has charged Assange with anything, to date. But should Assange be prosecuted for releasing classified information? Is our legal system prepared to deal with what’s become one of the most notorious information-heists of the Internet Age?

Julian Assange is seeking asylum in Switzerland, while his spokespeople say America should be concentrating on changing the behavior of its diplomats instead of hunting down the Wikileaks founder. 

British authorities are reportedly aware of Julian Assange's whereabouts in the South of England. But according to British newspaper The Independent, they have yet to act on the international "red notice" from INTERPOL, which alerts countries they are looking for him. Why? We're joined by Mark Hughes, crime correspondent for The Independent, to learn more on the story.   

On of the United States' largest concerns in the Middle East has long been the relative security of Pakistan, and more specifically, the security of that country's nuclear weapons. America provides millions of dollars in aid there, and the Pakistani government is considered an ally in an unstable area of the world. But in a country where the Taliban and other organizations have infiltrated the state military, it's a constant balancing act. 

If you offer to pay somebody to commit an act of terrorism, and then once they begin to prepare, arrest them for terrorism, are you catching terrorists or entrapping the unstable? This is a question being debated in several recent cases, including the recent arrest of Mohamed Osman Mohamud, who allegedly planned to bomb a Christmas tree lighting ceremony in Portland, Ore.

As journalists dig through some 250,000 documents released by Wikileaks for the details, big-picture questions abound. We've been asking listeners: Is the Wikileaks documents' release anti-American? You had a lot to say on the subject. 

The Associated Press is reporting that the color-based terror alert system may soon be thrown out, as per recommendations by the Homeland Security Department to the White House. The new alert system will reportedly endeavor to be more descriptive, helping the public understand the specifics of the threat and how to respond. We take a listen to tape on the old system — in effect since 2002 — and discuss what the new one might deliver. 

We've been hearing from listeners about whether America should get more involved with the recent skirmish between North and South Korea. You had a lot to say, whether you were commenting from Australia, South Korea, or from within the States. 

North Korea's artillery attack on a South Korean military base and fishing island yesterday certainly got the world's attention; the U.S. is sending war ships to the Yellow Sea for exercises with the South Korean military, and China is calling for calm. But what was the real goal of the North Korean attack — or was there a national goal at all?    

Unless Congress puts forward an objection, the 30-day review is done; a $60 Billion arms deal between the U.S. and Saudi Arabia could be completed by midnight tonight. One of the largest ever single sales if completed, the deal would provide Saudi Arabia with advanced fighter jets and helicopters. 

Yesterday the first Guantánamo detainee to be tried in a federal civilian court was acquitted of all but one of the charges against him. In total Ahmed Khalfan Ghailani faced nearly 300 charges of conspiracy and murder in the 1998 terrorist bombings of the U.S. embassies in Nairobi, Kenya and Dar es Salaam, Tanzania.

When President Obama was awarded the Nobel Peace Prize in 2009, it was understood he was given the honor on speculation — part of a hope by many around the world that the new American president would reduce the threat of global nuclear war. Specifically, many hoped that President Obama could bring his stated plan to fruition: to help eradicate all nuclear weapons. The President himself admitted it may not happen in his lifetime, but a year after accepting his Nobel Prize, is the world any closer to freedom from nuclear weapons?

"Before I built a wall I'd ask to know
What I was walling in or walling out"

Robert Frost's poem "Mending Wall" might serve as a good start to the conversation over whether the huge fence the U.S.government is building to prevent illegal immigrants, terrorists and drug traffickers from entering the U.S. from Mexico is worth the effort and money.

Of all the commemorations of September 11th planned for this weekend, Pastor Terry Jones' "Burn A Quran Day" is almost certainly proving the most inflammatory. Jones has announced that with others, he will host a Koran-burning at the "Dove World Outreach Center" in Gainesville, Fla. this weekend. Jones has made international news with his planned action, drawing the ire of everyone from Muslims to Gen. David Petraeus, who says the Pastor's event will endanger U.S. troops abroad. The event has also brought out critics from within his own Evangelical Christian faith.
