HONG KONG: Hong Kong’s tech-savvy protesters are going digitally dark as they try to avoid surveillance and potential future prosecutions, disabling location tracking on their phones, buying train tickets with cash and purging their social media conversations. 

Police used rubber bullets and tear gas to break up crowds opposed to a China extradition law on June 12, in the worst unrest the city has witnessed in decades.
