Amid lockdown, the police of Mallorca, Spain, make rounds to all the villages in their jurisdiction. Their sirens wail and blue lights flash in the empty streets. They step out of the police vehicles in full uniform and with...a guitar?! "Uno, dos, tres...!" Serenading onlookers in balconies, the police sing and dance in the streets, spreading joy and raising spirits as quarantined citizens clap from their windows.
