"We didn't come out against the military ... Some individuals and leaders made mistakes and I want to hold them accountable for what they did," said Helmi Hassan, the father of a protester killed in one of the many demonstrations that turned bloody under military rule.
After the vigil ended, a few participants marched toward Tahrir Square chanting against the military. They were blocked from the square by security forces, who dispersed them with tear gas.
The "Maspero Massacre," named after the state TV building where armored vehicles rolled over bodies of Christian protesters and gunned down others on Oct. 9, 2011, was one of the worst incidents of state-perpetrated violence during the military rule.
Back then, Coptic Christians who compose nearly 10 percent of Egypt's 90 million majority Muslim population were protesting a major lack of security after Mubarak's fall. Intimidation and attacks by Muslim extremists were rampant, with the razing of a church in southern Egypt particularly crystalizing worries among Copts.
For many Egyptians, the violent breakup at Maspero knocked the long-revered army off the pedestal they had held it on over the years, driving anti-military protests that became increasingly deadly. Among those killed there was Mina Daniel, a prominent Christian activist who turned into a revolutionary icon.
While Wednesday's demonstrators may have mixed feelings toward the military, all voiced enmity to former president Morsi and his group, the Muslim Brotherhood. Morsi had honored Tantawi and his chief deputy with Egypt's most distinguished decoration.
