Is Egypt headed for another revolution?

Furious Egyptian protestors surrounded Cairo’s security headquarters last night after a police officer killed a 24 year-old taxi driver over a fare dispute. The protest follows a string of other public demonstrations against police excesses, unrest analysts say could lead to another uprising in the restive country.

Egypt’s Interior Ministry said in a statement officer Mustafa Feto accidentally shot Mohammed Ali after the two men had a disagreement: “The policeman pulled out his gun to end the fight but a bullet came out by mistake, killing the taxi driver.”

But protestors argued it wasn’t a mistake. Local news stations broadcast video footage of tearful residents amid people chanting loudly and calling for justice. They said the officer verbally insulted the driver and when he objected, the policeman shot him in the head.

Egypt’s state-run news agency reports Feto has been arrested.

Last night’s protest is the latest outburst in a string of opposition to police brutality in Egypt. On Feb. 12, hundreds of doctors crowded the streets after police officers assaulted two emergency room physicians in Cairo’s Matariya hospital. Protestors held signs that read, “Police are thugs” and “Dignity for doctors.” The doctors threatened to go on strike if authorities failed to hold the accused officers accountable.

Earlier this month, Italian student Giulio Regeni was found dead in Cairo, his body showing signs of torture. But Egyptian officials dismissed claims its security forces might be involved.

The security forces’ abuse of power contributed to the 2011 uprising that resulted in the ousting of former President Hosni Mubabrak. But many abusive laws still govern the country.

“These laws have, among other things, effectively banned protests, legalized emergency police powers, and expanded military court jurisdiction over civilians, leading to the imprisonment of thousands of people,” Human Rights Watch said in a review of Egypt’s government.

As the frustrations of Egyptians continue to erupt in a spiral of protests, some experts believe the only solution could be another revolution.

“I think there’s another outburst—a much more violent one coming,” said Mark LeVine, professor of Middle Eastern History at University of California Irvine. “And I think when it comes, it’s going to be the showdown that everyone knew would ultimately have to happen if Egypt was going to be a democracy.”
