In S01 Ep 3 "The Entire History of You" of the black-mirror series (where they store all their memories on a chip behind the ear), we can see :
- At security in an airport for example, a guard can ask somebody to show all events within a week to see if the person saw some specific people.
- Anybody can erase memories at will, leaving "a hole in the history"
These points seem contradictory : if a guard sees a hole in history, this could immediately raise suspicion.
Also there's a scene where a girl calls the police for witnessing a fight and she cannot do anything because she doesn't have a chip to prove what she says. Which means that those "memory chips" have a huge evidence weight...
Is memory deletion legally managed ? What would have happened if Liam went to the airport with a hole in his history ?
