People making confident assertions about the ethnicity of the white baseball cap guy, in particular, is one of the silliest things I've ever seen here...it's as bad as the "I can see evil in people's eyes" nonsense, when they are looking at people they already know are mass murderers.
Of course it's driven largely by hope, of course.
Well, the guy in the white cap looks exactly like my neighbor did 20 years ago. If it were 20 years ago I would think my neighbor was a suspect! My neighbor is from Lebanon.
