Could your favourite song be used to cover up the misdeeds of the police?
Officers across the US have been filmed playing music - out loud - on their phones in public. They weren’t hoping this unusual display would make them go viral on social media. In fact, the aim was quite the opposite.
Some officers believe that by blasting music while being filmed, the videos would get blocked by automatic copyright protection software and activists wouldn’t be able to post them online.
Should we be concerned by these attempts to evade scrutiny by gaming technology, and do they even work?
