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

It’s theater. They’ll take away your “explosives” and throw it in the trash right next to them, you know, in case it’s a bomb. If you ACTUALLY had an IED with you, the terminal would be evacuated and the bomb squad would try to remove it somehow.

At the same time you can take charged batteries with you that can be damaged and will burn hot and long and with which you could probably force some sort of emergency landing.
