THE military has warned 15,000 youth volunteers, recruited to help city police as part of a national discipline campaign, to avoid using violence. The youths, dressed in quasi-military uniforms, went on duty yesterday as the city's new 'prefects'. Their tasks include 'disciplining' jaywalkers, roadside vendors trading on improper sites, litterbugs and reckless motorists. 'We will take stern action against volunteers who are found violating the rules,' city military commander Major-General Wiranto was quoted as saying. 'Defiant members will be fired.' He said the volunteers, who are drawn from youth organisations, should inform violators of their wrongdoings in a persuasive and educative manner. The volunteers have been assigned to some of Jakarta's most visible and, according to authorities, violation-prone areas of the city. These include major bus and railway stations, the city's main thoroughfare Jalan Thamrin, and Blok M, a shopping complex popular with tourists. Tougher and less visible assignments include Tanjung Priok, the rough dockside suburb. General Wiranto urged the public to report any deviation in procedure by the volunteers - including violence - to the nearest military office. Military district heads and police chiefs are responsible for volunteers in their areas. Jakarta was chosen as the site of the pilot project for the national discipline campaign when it was launched by President Suharto on May 20, National Awakening Day.
