Cairo braces for another day of protests
...the cops are already being deployed.
It appears that the police, having been off the streets for most of Sunday, have now returned. There had been reports earlier that they would resume patrols on Monday, but Egypt's state news agency and Al Arabiya TV now say that deployment has already happened.
I think that’s possible. Monday is when the world will be on-line and watching again, so I’m sure they want it to look as if El Baradei (clearly Obama’s pick) is riding into Jerusalem on Palm Sunday. Acclaimed by the masses, dissent from no one.
