I was preparing to put Peter Turnley’s celebratory photos of Tahrir Square on this site when word came that Lara Logan of CBS had been brutally assaulted even as he was taking the pictures.

The photos are ones of marvelous triumph. A 2001 Nieman Fellow, Turnley is an expert at this kind of thing: when there’s a major event anywhere in the world, he makes his way to it and lets his camera rip. As he writes in the accompanying picture story, he decided to go from New York to Cairo only a few days before Hosni Mubarak resigned, and he got there just in time. He brought along extra camera equipment and played that old customs trick – had one camera in a camera bag and hid the rest – but his luggage was never examined.

There are more than 40 pictures that go with Peter’s article; I picked the one of the two young women in a crowd as the main illustration because of the time it was taken: 9:10 PM. It may have been at that moment, or not far from it, that Lara Logan was so brutally attacked. The CBS report simply said the assault occurred that night.

There are some serious, unanswered questions at this point. To me a main one is how the Egyptian army responds. It was soldiers and a group of women that saved Logan but an early report suggested the perpetrators may never be caught. That doesn’t sound right. Her rescuers were right on the scene as were scores, possibly hundreds or more of Egyptians who must have been horrified by the brutal attack by gangs of men on a lone, helpless woman.

So a main question is: What is the Egyptian Army doing: How hard is it going after these thugs? Possibly we’ll hear soon of arrests in this case, you’d think that would happen. It’s the right thing to do and it would generate some good will abroad. But the generals also would pick up some good will by offering a public apology. And a sizeable reward for information might help locate these animals. As yet I haven’t seen where there has been a public apology or a reward offered.

There are other questions for the press as well. Are news organizations providing enough security for reporters in dangerous situations? Will what happened in Egypt make things better for journalists in the Mideast, or will it embolden would-be attackers? Sexual assault on journalists is apparently more common than many of us may have thought, according to a blog by Lauren Wolfe of the Committee to Protect Journalists. And it’s an especially persistent problem in Egypt, writes Mary Rogers, a CNN producer and camerawoman who has lived and worked there since 1994.

This awful incident doesn’t take away from the enormous triumph of the Egyptian people; it couldn’t do that. But it does take away from the euphoria of the moment.
