So the acting and the story and the end of the series, as a TV show, is great. It closes things off and does pay off for the viewers who just want to watch the end of the story and get closure on the series.
But, OMG, is it a mess of holes.
Nevermind the gun timeline that has been pointed out by several other commenters:
Ex-cop loses his gun but doesn't report it... John Ross who is in jail for murder, is not guilty of murder, would be re-tried for perverting the course of justice, probably released having served >8 months... Billy Ross is only guilty of perverting the course of justice, probably released by >8 months... Lori Ross would be arrested and charged with perverting the course of justice, whatever revised sentence John Ross gets she would get the same (or similar)... The daughter and DJ would certainly not be staying with her, especially DJ who she has no real familial connection to: he is the child of her convicted murderer husband and the original murder victim, CFS are definitely taking him away to foster care...
