Tony Chung, a Hong Kong pro-independence activist, was forced to unlock his device for authorities on August 25th. Not by threat or at gunpoint, but by pinning his head against the wall in a Hong Kong shopping mall’s stairwell while holding his phone to his face – attempting to trigger its facial recognition to unlock it.
Chung shut his eyes and scrunched his face in resistance. So they forced his finger onto another phone’s fingerprint sensor, also to unlock it, but he had long disabled the fingerprint sensor on his phone. They then proceeded to demand passwords, that he claimed to forget.
