In an ideal situation, these awesome volunteers would be able to deliver the water to those stranded with no issues. However the situation is never ideal, and the last thing FEMA wants is more people to rescue or create a difficult situation for rescue efforts.
Bringing in water is a rescue effort, and it saves more people from suffering or dying from dehydration. No, the last thing FEMA wants is for people to see how useless and counterproductive they are.
