on the violence today in Egypt

I just saw the anti-Mubarak protesters building walls on the streets to keep back the pro-Mubarak people throwing rocks at them.

Neither the military nor the police is stepping in between the sides. Using bullets seems out of the question.

The protesters will have to defend themselves. They ultimately seem to have far greater numbers, and are building defensible perimeters.

However, they have no access to ambulances, which will be necessary for many of the injuries caused by the violence. And they are surrounded.

Regardless of what the military demands, however, the protesters seem committed to staying.

Is there anything you think the US can do to help? (see previous post for some thoughts from myself and others)
