    Shooting two guns at the same time does in fact look cool. That’s not a myth. Hitting two targets with two guns at the same time is really hard though.

          Supressing fire is all about distraction and area denial. You can defintely fire two handguns accurately enough to do that. You might not get all yours shots in the 10 ring but you could deny access from one direction of a street for example.

            Years ago when I did my armed securities training, we went to a hillbilly ass shooting range, that was basically just some dudes big ass back yard. Did the double gun thing. Turns out, almost everyone unconsciously aims with their dominant hand and tracks that with their non dominant. Meaning you’re basically shooting st the same target with both guns even when you think you’re trying to go for both targets.

            Some people, however, will just randomly shoot with their non dominant hand, and it’s incredibly dangerous how wide those shots go. Like, damn near beside or behind them. Humans, it turns out, are fucking dumb

              I can’t imagine double aiming like that, maybe slowed down a lot. i could see training alternating fire on a single target being possible with practice.

      This one seems the least believable to me, but I admit I have almost no experience shooting guns. Maybe you won’t be super accurate, but it would work if you were going for suppressing fire against multiple bad guys while trying to get to cover or something.

      I wonder if someone practiced exotropia and multi-focal tracking (or rapid mono-focal switching) if then dual vector shooting could technically be learned.

      Regardless if anyone attempts this, please post a video of your face while you do it. For science.

    Defibrillator:

    Weeeell, not exactly. A defibrillator is essential to restarting a heart under specific conditions, and greatly improves the odds of survival to discharge. If your patient is already wired up and you see them go into a shockable rhythm, you can go ahead and shock them immediately. Otherwise, you’re going to need to do some CPR to prime the heart before you deliver the shock. At that, it’s worth noting that not all rhythms are considered shockable (that is, experience a clinical benefit from being shocked), and asystole (flatline) is not among them. Source: am paramedic.

    The lock: depends. Notice they said a small bullet. A 12 gauge slug can change a lot of facts about a lock in a hurry. I can’t say it would blow a lock clean out, I think the mythbusters tried it with mixed results, but it’s sure as shit take care of a padlock.

    Aiming at two targets: more of a shitty technicality, but if you’re using a shot load in a shotgun, it’s perfectly viable to aim at multiple targets (in a target dense environment) at once. Your aim just has to be generally correct.

    Tracing a call: bullshit, especially with cell phones. Modern dispatching centers can generally triangulate a 911 caller’s position (if they’re in range of multiple towers) in under a few minutes, it’s a thing. If 911 can do it, you just know the feds can. Also, phone companies and phones keep records of what device pinged what tower and when, people have been convicted off of that data.

      I would like to add that a suppressor can render certain specialized firearms nearly silent if they are used in conjunction with subsonic ammunition. A suppressor can deaden the sound of the initial explosion, but a supersonic bullet will continue to create a sonic boom as it flies through the air. A subsonic round doesn’t create a sonic boom and as a result nearly all of the sound of firing comes from the initial explosion. If that explosion is well sealed and is funneled through the right supressor, nearly silent operation can be achieved. A good example of this is the Welrod used during World War Two, which was quiter than an airsoft gun and was only really audible at point blank range.

      TLDR, how quiet a gun gets with a suppressor is determined by the ammunition, the type of firearm, and type of suppressor. Suppressed gunfire can range from as loud or louder than a nail gun to as quiet as a sneeze.

        Worth noting that while a nail gun is pretty loud (if you’ve ever been around them without hearing protection), it’s still nothing on being near an unsuppressed gunshot. If you’ve never been up close when even a pistol is shot, it’s much louder then you’re imagining, and louder still than you’ve just adjusted your imagination to. Rifles are louder again.

          I know someone who has a suppressed, large caliber rifle which makes less noise firing than most rifles do racking. It’s really impressive what a well -designed suppression system can do with heavy subsonic ammo.

      To me this is why that point is especially misleading, the movie trope is that as long as you hang up the phone soon enough they can’t find you, but that’s obviously not how it works at all.

      My issue with the two guns thing is that the “myth” they present is that it looks cool. Which is subjective, and for many people it does look cool. You’re unlikely to hit with any accuracy, but you’ll look cool missing.

        My issue with the two-guns one is that they use stormtroopers as shorthand for being a bad shot. The only time they were “bad shots” was in A New Hope where they were under orders to be bad shots. They were supposed to let the rebels escape on the Falcon, there was a tracking device on it.

            It was explained in the scene immediately after the Falcon departed the Death Star. Tarkin and Vader discussed the tracking device explicitly, and the fact that their escape was deliberate. Leia also speculated about it right after their escape, saying that their escape had been “too easy” and that she thought they’d let them go. This is in the same movie. How can that possibly be a “retcon”? Retcon is short for retroactive continuity, as in something that’s made up after the book or movie came out to explain things that happened in previous books and movies. You can’t retcon within the very same script.

              To me, “letting them go” applies to things like leaving escape routes open, posting minimal guards, leaving the tractor beam unguarded and off, not “shooting to miss”. What, did they put out an announcement at the morning briefing, ‘hey everyone if you see a stranger on our secret base make sure to shoot at them but not too accurately, even if this leads to your death’. I don’t buy it.

                Yes. Exactly that. These are soldiers, they follow the orders they’re given. Indeed, they’re elite soldiers. The Emperor fully expects that if he orders them to their deaths they will follow those orders to the letter and die for him.

                They were ordered to let the Rebels go, while also trying to make it look like they were trying to capture them. That means shooting at them and missing, but only just missing. It means letting yourself get shot if that’s the only plausible way for those Rebels to escape. That takes incredible marksmanship and incredible discipline.

                Remember Obi-wan himself stated earlier in that same movie that “only Imperial Stormtroopers are so precise” when admiring the evidence of their assault on the Jawa sandcrawler. Obi-Wan knows what he’s talking about. And that happened first, so you can’t even call it a “retcon” by any standard.

                Again, this is all stuff that was explicitly explained in the movie itself.

    I want to add to #1

    It’s right, there has to be an electric activity for an electrical shock (a defibrillator) to work. But please do continue CPR with a flatline. It’s harder, but there is a chance that emergency response staff can restart the heart with the right medication, but only if you didn’t pause the circulation.

    Sometimes you see in movies how someone is restarting the heart with a hit to the chest. Dont try this. Chances are you cause more damage than good. It is is a real maneuver called Precordial thump, but is only effective when you see the arrhythmia on the monitor and do it the very second of it happening. Outside of an ICU or monitored environment its not useful and can be quite harmful.

    If a movie wants to be extra dramatic, there is the is the big ass adrenalin syringe right into the heart. Pulp fiction is one example. This is something that makes sense, when you watch a movie set in the 1950’s or so. But it’s not a practice anymore, because it causes more damage than do good. It’s also nothing a normal person could do at home, because chances are nearly zero for you to hit the right spot. The heart is a fragile thing, you can’t just stab it randomly.

      Precordial thumps getting dropped from the EMS scope made me sad (paramedic here). They have a lot of utility, especially for us because we’re pretty much on top of the patient the whole ride, so we’re generally going to notice when they code. The problem is that it’s a lack of training. Most people weren’t even asked to practice the technique, you just read about it and got a slap on the ass on the way out the door. I mean, can you imagine teaching CPR or intubation that way? It’d be a fucking disaster. Little wonder people were doing it wrong and causing harm.

      Imo, too often the medical field’s answer to “people are doing this wrong” is “fuck it, we’re taking it away”, when it should be “do more (effective) training”.

        The compressions are essential to make sure there is blood and therefore oxygen getting to the brain. Without it the brain is dead after a few minutes. Even if the heart restarts then, the patient is brain damaged.

      Yup. One that got me was the one about shooting two guns.

      “Aiming at two targets is hardly possible”… It’s absolutely possible. You can aim at two things all day long. If you’re firing two guns at two targets, having to aim at them isn’t really the issue.

      The issue is that any aim you have one either target is going to suck. Combined with the difficulty of simply holding a several pound hunk of metal at arm’s length, and having it violently shake around every time a round is discharged because you don’t have adequate control over it to keep it from shaking every which way.

      No sir. Aiming is not the problem. Actually hitting the target is the problem.

      Presumably would actually just reform back into a planet since if you blow up a planet the mass is still there, it has just being fractured. If you leave it a couple of years it’ll form back into a planet again.

            I’m not an astronomist, so my understanding of the definition of moon versus asteroids is fuzzy at best. That being said, as I understand it, there are several objects that aren’t visible to the naked eye that would qualify as moons, but I may be mistaken. As I understand it we have 1 moon that everyone can see, another 12-16 moon like objects that aren’t visible, and several hundred asteroids. All of these objects orbit The Earth, so they count as satellites of The Earth.

          When the Falcon drops out of hyperspace in A New Hope Han says:

          “We’ve come out of hyperspace into a meteor shower, some kind of asteroid collision.”

          Han didn’t consider it to be an asteroid field, it wasn’t named as such. It was smaller debris.

          The asteroid field in Empire Strikes Back isn’t given an origin on-screen, it’s just there. It’s obviously been there for quite a while, though. It’s got native megafauna living in it.

          I checked Wookieepedia and there’s Legends material that establishes a variety of different explanations for the asteroids, but they’re all natural and all happened in the ancient past.

    The drowning thing is spot on. Been there, done that, and I can swim just fine. Only way I’m alive is by chilling out, getting my lips above water and sipping air. Once I had enough to float, I floated.

    Forensic scientist Sue Black says that there’s no such thing as “forensic” science. It’s just science, the “forensic” part just means the science is being brought into the courtroom. People (from watching movies/TV) think the science conducted in such contexts is somehow different or more complex than that done in other contexts. It’s all the same processes and skills and expertise.
