Did Lee and Ling enter North Korea on purpose?

I was never as incredulous as some others about the idea that Laura Ling and Euna Lee might in fact have knowingly and deliberately crossed the Tuman River to enhance their report (not that I believe it's a slam dunk case that they did). In fact, I took the silence of their chivalrous cameraman — who managed to escape — as an indication that he didn't want to reveal something that would verify the charge of illegal entry. 

Now comes a KCNA report of a video where the two women supposedly taped themselves inside North Korea. It comes from North Korea, so its credibility is suspect from the get-go. 

UPDATE:

Sonagi gave hat tips to me and Joshua of One Free Korea (see side bar). Though Sonagi didn't actually link this post, if anyone then stumbles across it, this might be a good opportunity to provide a link to my original Won Joon Choe-endorsed post on the capture of Ling and Lee. 

[above: A man at Seoul Station watches a South Korean news story on Laura Ling and Euna Lee. This has nothing to do with the story, but since Seoul Station is in my actual neighborhood, I'm there a lot and frequently see the crowds of people watching the news, some drama, a comedy, etc. And I just want to say that I think it's journalistically lazy to keep capturing the same image — a crowd of people watching some story on TV — to represent some story in South Korea. Well, at least they're not conflating North Korea and South Korea.]
