The intersection of politics, journalism, and social media became even more striking over the past few days as student journalist James Karl Buck was arrested along with Mohammed Maree, an Egyptian friend who was helping him report on political unrest in Egypt.

In large part thanks to a Twitter post after his arrest, legions of onliners came to his virtual rescue, contacting the US Embassy and the University of California which quickly dispatched an attorney to Egypt to meet with authorities. Buck was soon on a plane out of Egypt, but his friend Maree’s whereabouts still appear to be unknown after a second detention by police.

Details of this remarkable and still very active story are at Buck’s blog. Maree’s wherabouts are still unknown as of this writing at 10:30 am Saturday.
