When 26-year-old Egyptian woman Nihal Saad Zaghloul was grabbed and assaulted on the streets of Cairo, she formed an anti-harrassment group. When the group held a peaceful protest, they were set upon by about 50 men who groped and beat them. Now, they've formed street patrols to prevent assaults before they occur. Nihal says the patrols are just the beginning and plans to raise awareness in schools and universities. "My ambition is to change how people view and act towards sexual harassment."
