In Hong Kong Protests, Faces Become Weapons

Just a heads up - the US gov't has complete access to your iphone with the fusion centers and such. They do not need to you to unlock your phone.

If you are participating in a protest and are afraid you will end up on a list, just leave your cellphone home and cover your face up. The US gov't are not above using the same tactics as the chinese e.g. going after you where you work and breaking into your home etc.
