@Tutanota thatβs literally what x-rays and metal detectors are for. Yes, your clothes have to be βsee-throughβ for a small number of people to make sure you arenβt carrying a bomb or something.
@erf456 X-Rays are limited in time and space, doesn't log what they see, informations doesn't travel everywhere, they can't be used when you walk on the streets, etc. I'm sorry, but I think you don't really understand how absolutely disproportionate, problematic, deeply worrying and easily abusable a mass surveillance on everyone communications is. @Tutanota
