Maybe TSA isn't something with water but, its does not dangerous liquid at all. I think this is too dangerous for bring the water into the checkpoint. It will be thrown it away from passengers' checkpoint. Instead, passengers must go to sterile area where need to buy the larger bottled water near the gates. I think TSA is stupid rules for banned bring larger bottled water. It doesn't have justifications against TSA/DHS. I think in the future TSA will eventually changed the policies. I knows bottled water had no evidence at all. Passengers were never bring the liquid explosives with bottled water. I think TSA is gravely mistaken from 2 years ago.
