Perhaps not an appropriate sentiment considering the situation, but I have had to deal with far too many Europeans explaining to me about how it is dangerous to be on the subway after ten or eleven, how no white person in their right mind would walk through Harlem or any other black neighbourhood at any time of day, and so on and so forth.

PS I won't pretend that I've never felt any worries walking around at night in NYC, but that's nothing compared to the feeling of seeing a bunch of drunken shaved headed young white men on a lonely street at night in Germany or Poland.
