A pawn being moved off the board

Clyde Shelton (Gerard Butler) is in a vendetta kind of mood for a truly good reason. His family is murdered and the culprits walk away with petty convictions. As good a reason as any to start murdering goverment officials. Altogether a very satisfying thriller with somewhat an anticlimactic ending, still one of the better ones at both Butler's and Jamie Foxx's career.
