The first mission or two will force you to play in the order, but after that, the city opens up for you and you can go to the flashbacks in any order you want. It was in an E3 interview with Joseph Staten. I saw so many, I'm not sure which one it was in. He said that players were wandering aimlessly. The first 2 flashbacks really get you settled into the city, and then you can go wherever you want.
