My second day in Cairo, I stopped for lunch after spending the morning in Tahrir Square. Just as I was heading back out to shoot, a few friends and colleagues came into the hotel with injuries. I checked out the scene from my balcony. Crowds were moving like waves, rocks were flying in every direction, and gunfire was ringing out.
