* Five young peace activists handcuffed themselves to the front door of the Armed Forces Recruiting Center Wednesday in Philadelphia.
For 4- hours they stood, linked wrist to wrist, as hundreds of other student protesters held placards, chanted and cheered in front of them in the middle of Broad Street, snarling traffic for blocks. They even formed a human peace sign.
In receiving-line fashion, fellow protesters walked up to thank the three women and two men who represented various student groups. The student-organized protest started about noon when dozens of area high school and college students walked out of class to join the 4 p.m. rally around City Hall. About 200 University of Pennsylvania students walked out at 2:40 p.m., then marched in a zigzag to Center City.
