Protesters, police go online in G20 battle

Social networking Web sites are set to play a crucial role in protests ahead of next week’s G20 meeting of world leaders in London as demonstration organizers and police use Twitter and Facebook as key sources of real-time information and intelligence. Metropolitan Police leaders have warned that the city faces an “unprecedented” wave of protest in the run-up to Thursday’s summit talks on the state of the global economy and are set to deploy huge numbers of officers to maintain public order.
