Liberation Square in Cairo has been ground zero for a series of government-rattling protests across Egypt. On Tuesday, the largest crowd yet -- a quarter million people -- gathers on the square as a youth stands on Egypt's national flag. For the protesters, the rally capped a week of an unceasing, and sometimes violent, push to force the ouster of President Hosni Mubarak after nearly 30 years in power.
