According to the BBC report she was actually rescued by a group of Egyptian women and soldiers. I certainly hope arrests were made.
And I agree with Christian73 on this. Given our own country's record on violence against women, it's hard to assume the moral high ground.
And as for the laundry bag comments, in the Middle East patterns of dress and codes of religious conduct vary widely. Saudi Arabic exports variations of Islam that are the most conservative, but in countries such as Egypt standards of dress for women are neither enforced in law or necessarily uniform. Any cursory research shows that it is as much a form of political statement and personal expression as the following of religious doctrines.
Finally, I think the anti-reporter sentiment stoked by the Egyptian Interior Ministry and its thugs has much more to do with the incident at hand. http://www.bbc.co.uk/news/world-middle-east-12476771
