There has been talk about, but no movement on, a government investigation into the violence, which occurred at a sit-in by supporters of former President Mohamed Morsi, who was ousted by the military in July. The work has been left to the semiofficial National Council for Human Rights, which has no power to compel officials to testify.

Ragia Omran, a council member, said they had started to interview witnesses and review videos of the violence. She said she had faith there would be justice, eventually. “It will happen later on,” she said.

In the meantime, the country has not even been able to agree on the final death toll, and the authorities have released conflicting figures. They have said that between 683 and 1,000 people, including 43 police officers, were killed across the country on Aug. 14, the day the authorities stormed Rabaa al-Adawiya, as well as another sit-in by Morsi supporters at Nahda Square. Mr. Morsi’s Islamist movement, the Muslim Brotherhood, has released figures widely seen as inflated, claiming that thousands died. Other reports have put the number at between 800 and 900 people.

There is little clamor for any inquiry among the public, which harbors deep antipathy toward the Brotherhood and seems desperate to move on from the era of protest. Despite a crackdown on the movement, Mr. Morsi’s supporters have continued to march. They have adopted the name of the square as their slogan, and the four-finger symbol that has become its own provocation.

In recent weeks, two Egyptian athletes have ignited controversy after flashing the symbol at sporting events, a gesture, they said, to the people who died. One of them, Mohamed Youssef, who wore a Rabaa T-shirt as he was receiving a gold medal at a kung fu competition in Russia, received a yearlong suspension from competition by Egypt’s Kung Fu Association, according to local news media.

On Sunday, a soccer player, Ahmed Abd el-Zaher, flashed four fingers after scoring a goal for his club, Al Ahly, shortly before it won the African Champions League title. Egypt erupted in jubilation over the victory, but Mr. Abdel el-Zaher was suspended from playing with the club, which on Tuesday announced that it would transfer him.

Since the uprising almost three years ago, anniversaries of serious abuses come and go, without justice or recognition for the victims. Instead, they are memorialized with graffiti, which the authorities periodically try to erase. Next week, activists are expected to commemorate the anniversary of demonstrations two years ago that ended with the deaths of 45 protesters.
