Most mainstream news reports concentrate on Mubarak's health and pair this with the large crowds in Tahrir Square apparently to suggest that the two events are related. This treatment, of course, detracts from the reality of what is happening in Egypt.
In my estimation this source provides the most accurate assessment about what is actually happening there.
An estimated 50,000 people took part in protests in Cairo’s Tahrir Square yesterday against last Thursday’s coup and the establishment of a military dictatorship by Egypt’s Supreme Council of the Armed Forces (SCAF). Another sizable demonstration took place in the port city of Alexandria.
