"I’ve just returned from the first demonstration ever to take place against Mubarak’s rule — a significant milestone in the evolution of Egypt’s pro-democracy movement.
"There were some 500 activists, mostly from left-wing groups and human rights organizations, who gathered near the highest appellate court in the land in Downtown Cairo — the same place that overturned the verdict against Saad Eddin Ibrahim a couple of years ago.
"As usual, they were surrounded by an incredible number of black-clad troops from Central Security, the riot-control police, who must have been in the thousands around the demo and in the surrounding streets."
There's a lot more there - like with Chana'd Bahraini's great on the ground coverage of the Khawaja protests over the last few months, this is really fascinating stuff. Amrani gives a bunch more details, and promises to have videos and more information posted soon.
(link fixed, thanks. El Amrani has added more details, too.)
