Of all the freedoms Egyptians thought they had won with the Tahrir Square Revolution, the one they thought irreversible was the right to demonstrate.
Hundreds of young protesters were killed during the uprising against Hosni Mubarak that began exactly five years ago today. The "Angry Youth" stirred the hearts of the world as they marched, prayed and sang their way to overthrowing 30 years of President Hosni Mubarak's dictatorship.
The family of Mahmoud Mohammed Hussein might beg to differ. Mahmoud was just 18 when he was arrested on the revolution's anniversary two years ago, after attending a commemorative event in a T-shirt with the seemingly uncontroversial logo "A Homeland without Torture".
In those two years, he has been moved from jail to jail without ever being charged or being brought before a court.
"Mahmoud is growing up in prison," his brother, Tareq, told the Daily Telegraph.
