Even beyond the legal aspect and knowledge of the system, it must be quite difficult, in some cases, to simply arrive and trust another human being enough to tell that person your story. If in addition that other human being is an official associated with the authorities, with the government, and you come from a country where you've been persecuted, that seems to be even more difficult.
The government is putting forward these provisions, the interview and the time period before the interview, among others. Running through this we clearly see the idea that some people lie and that these provisions will leave them less time to make up a story. They're going to be asked to tell their story orally rather than on paper. They'll be able to ask them questions.
Isn't it instead the reverse that could well occur? Those who simply make up stories may perhaps do better in this system, whereas the most traumatized individuals could well have more trouble dealing with it.
