Meet the new bosses, same as the old ones. Protesters in Cairo calling for a faster transition to democracy were attacked by knife-wielding men Saturday on their way to the headquarters of the military government. A crowd of 10,000 people marched from Tahrir Square but was stopped at a line of army barricades. Men armed with sticks and knives charged at them from side roads, beginning pitched street battles. Former ruler Hosni Mubarak often used gangs of thugs to put down protests. The army denies it used force against the protesters.
