It is, however an outrage that we have a rule directed against a nonexistent threat, which prevents people from bringing in water and other liquids for drinking, and the response to complaints is "oh, bring a bottle and get water from the water fountain." Maybe people think the water fountain water is dirty and it isn't; maybe they think it's dirty and it is; maybe they sterilized water at home and used it to make baby formula. None of that should make any difference; the reasons shouldn't matter (especially in the case of baby formula). The only thing that should matter is that LIQUIDS AREN'T DANGEROUS.

As I understand it, the rules in the US are pretty good - a liquid is a medical liquid if the passenger says so. If the clerks could be counted on to follow the rule, the result would be pretty satisfactory.
