Ugandan Demonstrators Painted Pink

Some may be wondering why Yoweri Museveni opted to spray demonstrators with a pink substance instead of simply using the usual fire hoses and tear gass canisters. I have a theory: he wants to know his enemies. Painting them with the liquid makes them more visible and so they can be identified even as they return home. It would then make it easy for him to send his secret police so that these demonstrators can be picked up even after the demonstrations. If he sprayed them only with water, they would not stand out in the crowed as much as they would be if sprayed in pink. Museveni has a strategy. We are have not heard the last of it.
