I've always been irritated by the prevalence of the Polish Jew Theory. I don't care how many eyewitnesses mention someone "foreign" looking, given Victorians, I just can't take that as meaning anything at all.

There's an A&E special on Jack the Ripper where Douglas gives that same profile; I remember watching it in high school when I wrote my senior English paper on Jack the Ripper. (Well, they told us to pick whatever topic we liked...)
