Answer:
Yes it is reasonable to require all airline passengers to submit the full body imaging.Because we know that there are lots of person who want to produces violence and these person travels with some guns ,explosive etc.To protect all the good person it becomes necessity to check all body before entering in the air plane.By doing this all person feel safe from any violence.But lots of people are asking that this is not right because this against the rule .In my opinion life is more important than the others things.
