When journalists Laura Ling and Euna Lee were captured by North Korean forces on the border with China in March  we had questions. What were they doing there? Why were they taken? Why was their employer, the viewer participation cable news pioneer Current TV, staying silent about the case? Even to the point of censoring viewer created content on the subject?

Last night Ling and Lee issued a written statement about their imprisonment and the events leading up to it, with a focus on the story they were there to pursue: the plight of North Korean defectors in China.

In their statement published on Current, the pair paint a dramatic picture of their capture:

Feeling nervous about where we were, we quickly turned back toward China. Midway across the ice, we heard yelling. We looked back and saw two North Korean soldiers with rifles running toward us. Instinctively, we ran.

We were firmly back inside China when the soldiers apprehended us. Producer Mitch Koss and our guide were both able to outrun the border guards. We were not. We tried with all our might to cling to bushes, ground, anything that would keep us on Chinese soil, but we were no match for the determined soldiers. They violently dragged us back across the ice to North Korea and marched us to a nearby army base, where we were detained. Over the next 140 days, we were moved to Pyongyang, isolated from one another, repeatedly interrogated and eventually put on trial and sentenced to 12 years of hard labor.

The answer to the most baffling of the questions raised at the time-- why was Current remaining silent-- comes in at an unexpected angle, and sheds light on the character of Ling and Lee:

Supporters of jailed journalists Laura Ling and Euna Lee will gather tonight on the steps of San Francisco's City Hall at 6:30PM for a vigil and group photo.

The event's organizers report that mail has been getting through to the pair, whom North Korea recently sentenced to 12 years of hard labor. Those in attendance will be asked to write personal messages that will be sent to the two women along with the photo.

The planned vigil comes on the heels of Ling's sister, television personality Lisa Ling, reporting that her sister telephoned her on Tuesday.

This week we've been following the sentencing of Current TV reporters Euna Lee and Laura Ling by North Korea to 12 years of hard labor with intense interest.

As journalists, this story strikes close to home. On top of that, there's the curious silence of Current TV- whose only official reaction, so far, to both the capture and sentencing of their reporters has been "No Comment". On Tuesday we spoke with journalist Josh Wolf- who holds the record, at 226 days,  for the longest prison stay by a reporter in the United States for protecting source materials- about his own investigation into why Current has been staying mum.

Josh's willingness to serve time, and Lee and Ling's very presence on North Korea's border to tell the story of human trafficking, speaks to the nature of reporters. Call it daring or just plain crazy: putting yourself at risk to tell a story isn't exactly "normal". So we went to visit Josh in San Francisco to talk to him about why reporters put themselves in dangerous situations.

Current TV journalists, Euna Lee and Laura Ling were sentenced to 12 years of hard labor after being charged with crossing North Korea’s border illegally. The details about their crossing are unclear.

Being a journalist means reporting the facts and making sure the story makes it out to the people. But along with that duty comes obstacles. That’s what Josh Wolf, Staff Writer for the Daily Post and independent reporter faced. Wolf has been following the story of Current’s reporters very closely, and not just because it’s making headlines: Wolf served prison time for sticking to his principles as a reporter.

We conducted this interview about Current TV's curious silence with Wolf online today:
