From MSNBC / AP :
The late Tuesday assault was the last straw for many. Protesters and activists met Wednesday to organize a campaign to prevent sexual harassment in the square. They recognize it is part of a bigger social problem that has largely gone unpunished in Egypt. But the phenomenon is trampling on their dream of creating in Tahrir a micro-model of a state that respects civil liberties and civic responsibility, which they had hoped would emerge after Mubarak's ouster.
'It shouldn't be happening'
"Enough is enough," said Abdel-Fatah Mahmoud, a 22-year-old engineering student, who met Wednesday with friends to organize patrols of the square in an effort to deter attacks against women. "It has gone overboard. No matter what is behind this, it is unacceptable. It shouldn't be happening on our streets let alone Tahrir."
No official numbers exist for attacks on women in the square because police do not go near the area, and women rarely report such incidents. But activists and protesters have reported a number of particularly violent assaults on women in the past week. Many suspect such assaults are organized by opponents of the protests to weaken the spirit of the protesters and drive people away.
