The new CDIA, for its own part, revealed some impressive new tactics. The CDIA lacked the legal power to arrest anyone, so they pursued Emergency committee members with nonviolent "body pickets." These were armbanded bursars who methodically stalked committee members for twenty-four hours a day. This tactic was not difficult for a prole group. "Body picketing" was basically an intelligence stakeout, shadowing; but it was not surreptitious. It was totally open and obvious, and like all paparazzi work, it was extremely annoying to its victims.
