for the last few days, sara sidner's (and her crew's) reporting from libya for cnn has been astonishing. she rolled into tripoli from zawiya with the rebels and straight to green square when the rebels reached it. today she was actually reporting from inside the gaddafi compound as the rebels took it, right inside the firefight, chaos, and celebration. now she's back in green square. really, amazing, not least for extreme composure under fire.
