On October 3rd, 2017, Associated Press photographer Evan Vucci photographed Donald Trump shooting rolls of paper towels as if they were basketballs into a crowd hurricane victims in Puerto Rico.
If he had tossed water/food packs into the crowd he would’ve risked injuries in the crowd from the packs hitting someone in the face or the people scrambling to grab them, which would’ve resulted in a PR disaster.
Better to leave the food and water distribution to the aid stations.
Also, paper towels help with the sanitation needs of the people, which in turn lowers the risk of disease spread that is a huge risk in disaster areas due to stagnant water and people with compromised immune systems thanks to injuries, malnutrition and temporary poor hygiene conditions. Also they’re useful as arsewipe.
