So, being responsible for the death of a couple cops is no big deal
-- SPOILERS --
At the end, when Graham takes it upon himself to storm the house, he sets off a chain reaction that leads to Dollarhyde blowing away two fellow cops. This, presumably, wouldn't have happened if SWAT took the house, as planned.
After the dust settled, nobody mentions this. Graham doesn't express any remorse & Crawford doesn't lay into him for going it alone. No repercussions.
Overall, I dug the film, but, I don't know. That bugged me.
