Jim Beckett "I've already lost my wife over this...I've already lost [pause]. It took me years to make my peace with them"
Montgomery "I could protect you the way I should've protected her"
Her? Seems to refer to Johanna Beckett, but why should he say he shouldn't protected her. Seems more than saying he should protect a regular citizen as a cop back then. Did he know Kate's mother?
Montgomery "He could've turned us all in, instead he asked for the ransom money..." Someone who could turn 3 dirty cops doing incarceration but instead is powerful enough to keep it quiet and demand something for his silence would be? A powerful enough cop?
