The larger demonstration back at Tahrir was about issues closer to home: Egyptians are demanding that the military transfer power quickly to a representative civilian government, after the death by torture of a 24-year-old political prisoner named Essam Ali Atta. As the Guardian reports, critics say his death proves that the junta is failing to dismantle Mubarak's brutal security apparatus:

Essam Ali Atta, a civilian serving a two-year jail term in Cairo's high-security Tora prison following his conviction in a military tribunal earlier this year for an apparently "common crime", was reportedly attacked by prison guards after trying to smuggle a mobile phone sim card into his cell. According to statements from other prisoners who witnessed the assault, Atta had large water hoses repeatedly forced into his mouth and anus on more than one occasion, causing severe internal bleeding. An officer then transferred Atta to a central Cairo hospital, but he died within an hour.

His funeral took place today. Follow live tweets from the memorial at #esamatta. Journalist Reem Abdellatif, who is there, tweets:

His sister just passed out screaming they took my brother from me. [photo]. The scene is devastating at the morgue #essamatta's mom and sister keep calling out to him like he's still alive. Essam was 24.
