Why do we have to surrender all the water before entering the airport even if we prove that is in fact a drinking water by taking a sip?

Question

But once inside the airport terminal, we can always buy some water and no one will check anymore if you bring the water inside the plane.

Answer 1

Some possible, less cynical answers:

* nobody is forced to drink something that might put them at risk (e.g. minor being forced to smuggle something on board)

* it’s more reliable to have a blanket ban rather than a case-by-case drinkability test
