D.C. officials have put cameras on light poles, police cars and government buildings. Now they're preparing to put them on street sweepers in the latest example of increasing surveillance of city residents.The D.C. Council yesterday unanimously passed legislation introduced at the request of Mayor Adrian M.

The city also operates 74 surveillance cameras affixed to light poles and buildings in neighborhoods as part of an effort to deter crime.But critics have charged that the latest devices serve as a moneymaker for the city and an intrusion on privacy instead of a public safety tool, as officials contend."The greater concern for us is the expansion of the program," said John B. Townsend II, a spokesman for AAA-Mid Atlantic. "I think it's hard to say to people that revenue is not one of their ulterior motives."Scheduled street-cleaning service takes place weekly in every city ward except for Ward 3, and it is temporarily suspended during winter. Signs prohibit parking along curbs during a two-hour window while the service occurs, and violators caught by the cameras will receive a $30 citation in the mail.Linda Grant, a spokeswoman for the D.C. Department of Public Works (DPW), which operates the street-sweeping program, said the legislation will provide the agency with an added tool to clean streets without obstruction and rid neighborhoods of trash and toxins.DPW officials say parking control officers are able to enforce street-sweeping regulations on only about 20 percent of the routes.As in the days of Noah....
