Counter-Terrorism and Border Security Bill

I am grateful to the Minister for giving way. If somebody is coming through a port of entry and their passport is examined, and in the moment of examination it becomes apparent that there is something about the passport that does not look quite right—for example, there may be very few entries in it whereas the person concerned looks to be a sophisticated traveller—would not such a situation fall well short of being reasonable suspicion but be a proper exercise of the ability of good officers to use intelligence applied in the moment?
