Plot hole: Since they took down the telephone network, it would have been impossible for Justin Long to even be speaking to the emergency response woman for the car, much less send a signal to start the car up.
Suggested correction: Is it possible this is a satellite phone call akin to Onstar?
No, the BMW system requires a cell signal to work, which was taken down earlier in the movie.
Plot hole: Spoiler! We find out that "Rogue" is actually Tom Lone, who killed the real Rogue and destroyed his face to prevent identification, then had plastic surgery and went underground to get revenge. But how is the body never identified? Lone was a cop, they'd have blood type, DNA etc. on file, which would have proved the body wasn't his.
Plot hole: To rig blackjack card shuffling machines to make the dealer bust and everyone else get 20 or 21, its success would depend entirely on knowing the exact number of people at the table at that time. Perhaps the filmmaker is assuming all seats at the high-stakes blackjack tables would always be filled during a "soft" opening, but that seems extremely unlikely.
Plot hole: Turner locks himself and Ashley in her car so he can confront her. However after his speech, Turner somehow manages to open the door without unlocking it.
Suggested correction: It is accurate that Turner can open the door without unlocking it, all modern cars can be opened from the inside whether the door is locked or not. Ashley never actually tries to open the door, she reaches for the handle and stops once Turner locks the door. Since the movie never actually shows Ashley try to open the door, this doesn't count as a plot hole. If anything this is a character mistake, Ashley should be well aware that she can't be "locked in" a car that new.
Plot hole: When Agent Memphis is about to be executed they ask him if he needs to "Piss" so as to not have government-used drugs in his system before he commits suicide. They even mention writing a suicide note for him. He's had seven shades beaten out of him though and was kidnapped whilst on the phone, mid-conversation and with possible witnesses. Surely if it wasn't the first time they had done this then they would have taken more care to make sure it wasn't a complete fake-out.
Plot hole: When Detective Broussard is killed and Patrick was being interviewed by police (dressed in a white shirt), the interviewing police detective say "a couple of nights ago you were at the quarry." In fact it was months before when they were trying negotiate the release of Amanda at the quarry. It unravels the entire movie.
Plot hole: *SPOILER* Toward the end of the movie, Ryan Gosling goes to Hopkins' house where Hopkins is tricked into not only confessing again, but giving Gosling the murder weapon, after they are back in court and Gosling is the acting prosecutor. This would be a conflict of interest due to the fact that Gosling is a witness.
Suggested correction: First, the gun that Beachum took from Crowford's house was not the murder weapon. It was Crowford's unfired gun. He only took it out of the fear of his life. Second, Beachum entered Crowford's house with police supervision. If he plays it by the book, Crowford's confession is valid. In that case, supervising officers will stand witness, along with a recording confirming their testimony. Third, Beachum doesn't need the confession anymore. He was amply clear on that matter.
You are on point for the corrections, but they involve just mostly context/details, don't they? The text of the entry should be polished a little, but the core issue is valid, I think; Beachum would never be the acting prosecutor in a case when he is the key witness as well. If it's a case for the "murder," he has to be on the stand for practically everything; even if we exclude him from the confession to the shooting, as you suggest (and even if it should never be litigated to begin with), he still is integral to the pulling the plug phase (he was literally there as it happened and did everything to prevent it). We can just assume that he will be forced to hand the prosecuting role over to someone else later, and he was just there for 5 minutes to gloat before the movie credits run, but it's kind of funny.
Beachum doesn't have to testify, neither for the confession part nor for the "pulling of the plug." I've already covered the former. For the latter, the fact that the woman is now dead is enough. If necessary, the attending doctors could testify that the woman "would have outlived all of them."
Beachum received the confession under "police supervision," as you called it, which still involved him being the only person in the house with the defendant. You mentioned a recording in the earlier comment; are we just to assume he took one, or is there a visual hint I missed? He was also the person who fought for the court order to the point of being physically tackled in front of the victim's deathbed—so doctors and security staff defiant of such an order would be on trial too, I suppose? Since, again, this 'murder' was not even committed by Crawford. So how would Beachum not be a crucial witness, often the only witness to cover that part of the story?
OK. You want to assume Crawford's confession was for the viewer's benefit entirely, and there was no wiretapping? Fine. The police have the gun now, hence proof of the first actus reus. Hospital staff tackled Beachum, but Crawford can't pin the murder on them when he has two counts of actus reus and twice demonstrated mens rea. Courts always hear such nonsense as "I didn't kill him; I shot him. The bullet and the fall killed him" (Collateral, 2006). Shooting someone is actus reus.
I am sure you are right on the Latin, especially since it's hard to imagine the trial going the way it went the first time around to begin with, and I am not getting into the rabbit hole of what exactly could legally be relitigated. But still and again, what does this have to do with the original point being made, that some other guy would be the one leading the trial, since Beachum would be realistically called in as a witness, even a hostile one? I mean, I honestly didn't think it would be much of a point of contention; it's just something there for the audience. I followed the lead about the 'witness' part the OP ended on, but seriously, a conflict of interest would be invoked just because of all the personal first-hand, hands-on involvement in the facts.
I explicitly told you what happens if the court struck the confession from the record. (The gun happens.) And yet, here you are, saying "Beachum would be realistically called in as a witness"! This correction is turning into a confrontation. Also, don't conflate "involvement" with "conflict of interest." The latter means someone has different de facto and de jure motives. Beachum always had one motive: to convict Crawford.
Far from me to be confrontational, and sorry if I came across that way. I guess I simply don't get it; it happens. Specifically, if I stated again the point about the witness, it wasn't because I was blindly disregarding what you said (check the words immediately after the ones you quoted), but it's pointless to delve further into something that goes beyond the original mistake. You just directly addressed the meaning of conflict of interest, which was what the OP talked about. I simply felt the initial correction posted was not doing that; now it does, and I am not disputing your knowledge on the topic, especially not having any of my own. Cheers.
Plot hole: In the scene where 47 swings out of the hotel window, we see the booby trap starting to explode as he's still in the room. Then in the shot from outside, the explosion extends out the window - so how on Earth did he outrun it and get out completely unscathed?
Suggested correction: He escaped before the debris from the explosion reached him. If you watch in slow motion, you can see that he was ahead of the debris whilst in the room, then below it when out of the window. And even if he had been hit by some, it wouldn't have been a plot hole, unless he was killed or seriously injured.
Plot hole: Brewster gives Erica his gun to shoot the last perp, but it was HER gun that shot the other two. Brewster is going to have to convince investigating officers that the one perp killed the other two...or would they even care?
Plot hole: This could be a "suspension of disbelief" issue, but at the climax of the movie when the murderer's accomplice gets shot, Jack has to grab the rope to save the dangling Dean. Objects (including people) fall at 32 feet/second, and speed up after that. That's roughly 10 yards/second, which is the speed of a world class sprinter. Jack was a speedy fellow to get to that rope, especially with street shoes, no starting blocks, and a slippery surface to boot (not to mention his age).
