Where was Lara Logan's security for 20 to 30 minutes?

CBS news journalist Lara Logan was assaulted in Egypt. She had become separated from her news team and protection detail. Several questions: How many protectors does it take to be "safe" in a mob? Tahrir Square is a large place, capable of holding tens or hundreds of thousands of people. Once separated from their protectee (Logan), where did the protectors go? I read that she sustained prolonged (20-30 minutes)assaults before being rescued by women and Egyptian soldiers. Where were the tactical observation posts? Were there any? Why or why not? Total breakdown in planning here. Something smells...

Happy New Year, 2011!
