Egypt has sought to distance the police from the weekend shooting death of el-Sabbagh, saying a forensic examination shows she was killed by a type of projectile that is “absolutely” not used by security forces. A senior official from the Interior Ministry, which is in charge of the police, also dismissed as “inconsequential” video clips showing two masked, black-clad policemen pointing their rifles in her direction as gunshots rang out and a voice commanded “fire.” (AP Photo/Mohammed El-Raaei)
