Which places besides the bars and homes would black people be able to freely socialize (where there is no white supremacy) in Devil in a Blue Dress?
The very different environments in which Easy is forced to work in this text to make ends meet present us with the segregation present in America at the tme of the novel and the double standards of the white-dominated justice system. As Easy ventures both through the "dark streets" of places where non-whites congregate and also through respectable white neighbourhoods, the reader is able to see the radically different settings where characters are treated and thought of so differently.
In particular, what is interesting is the way in which Easy finds there is a curious solidarity that is shared by African Americans and Jews and latinos. There are clearly areas such as the barrios and neighbourhoods where these groups of people live where such people can enjoy the illusion of making their own rules and living their own lives, and to a certain extent, the white police's indifference to what goes on in these areas where whites do not live mean that this is not an illusion. Note what Easy discovers when he visits the neighbourhood called El Barrio:
...a Mexican and a Negro once considered themselves the same... just another couple of unlucky stiffs left holding the short end of the stick.
Therefore, the places that this text show non-whites as having the ability to rule themselves free from white supremacy are any of the places in their own neighbourhoods, where the police do not venture.
