Two indigenous high school seniors on a tour of Colorado State University were removed from their tour by police because someone thought they were vaguely suspicious.

I wonder whether they still want to enroll there.

The first time I went to an academic conference, to present my paper on Emacs, I was harassed on two occasions by hotel staff who doubted my right to be there. Since I am a white male, I think I was treated as suspect because I didn't (and never do) wear a business uniform (suit).
