Imho, and I don't have any hard evidence, but I believe Valarie Jarrett would be capable of killing large numbers of people without remorse. She is an ideologue. Her parents were ideologues. I have seen this type behavior and personality traits throughout history, and the results are always the same. It always ends badly. All of the Leftists are like that. They believe there is no problem the summary execution of a few million people can't solve.
In the name of peace and for the children, of course.
