Never really considered Little Ulster as mini-Detroit, myself. Sure there was crime there and it wasn't the best neighbourhood (in fact probably the worst of the 4 quadrants), but I viewed it as a once-fine sector which has seen better days because of that crime. Saw old Irish family crime gangs (kind of like in The Departed only a little grittier, in my head)

Not expecting to hold anyone to that view though.

Plus, in my mind as an outsider I virtually see Detroit as a war zone... heh.
