Van Jones states that only white kids commit mass school shootings. It sounds like the sort of thing that might be true, though the sample is so small that it might not mean much even if it is true. But it turns out not to be true. The link above leads to Helen Smith's "reality based" discussion.
Here is Mark Steyn's take on Van Jones' signing of a petition asking for investigation into whether the 9/11 attacks were an inside job. His take-away: if you really thought there was reason to investigate you wouldn't sign a petition asking for an investigation. After all, a regime ready to bump off 3000 citizens to justify a small war would think nothing of bumping off a couple of whistle blowers.
