If you read each one of these stories about a measles scare, you get to the part where the carrier was recently "vaccinated" and it caused - not prevented - measles. Caused. Not prevented.
Black people riot over some thug shot by a cop who exhausted every other means to arrest him but completely fail to realize when white "doctors" knowingly inject their kids with a vaccine seven times more likely to cause complications in their children. Wait, it gets worse. They were injecting black kids with an experimental measles vaccine without notifying the parents beforehand or getting their permission and telling them their symptoms had nothing to do with the vaccine after they developed. They told me the same thing when my son had a reaction to the MMR. This stuff starts to sound like testimony from Nuremberg at some point about Dr. Mengele's cold water research lab.
If a city got burned down, you'd expect it to get burned down over something like that. Instead they riot over routine police work.
