This is actually one of my favorite episodes of the 6th season. When it says it is based on a true story, I actually think it is based more on the documentary "Street Fight" which chronicles the race for mayor between a young, fresh-faced challenger (Cory Booker) and a sixteen-year incumbent (Sharpe James) in Newark. I thought that the murdered character, Dex, was very likeable, and the ending was thus very tragic. And it showed the corruption that still does taint Philadelphia politics, and is actually rather realistic if you watch "street fight". A solid story that we haven't seen from Cold Case as much in the last season or so.
