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.

[-] Diplomjodler3@lemmy.world 26 points 4 months ago

If you're trying to lay down suppressing fire, it'll work, though.

Also, in most media I've seen, people with two guns still primarily shoot at single targets

[-] pastabatman@lemmy.world 3 points 4 months ago

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.

[-] Septimaeus@infosec.pub 2 points 4 months ago

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.

[-] conditional_soup@lemm.ee 14 points 4 months ago

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.

[-] LowtierComputer@lemmy.world 4 points 4 months ago

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.

[-] chicken@lemmy.dbzer0.com 28 points 4 months ago

Also, phone companies and phones keep records of what device pinged what tower and when, people have been convicted off of that data.

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.

[-] Hawke@lemmy.world 7 points 4 months ago

It is how it used to work back when these tropes came about.

Here’s an interesting video on the topic

[-] dylanmorgan@slrpnk.net 21 points 4 months ago

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.

[-] FaceDeer@fedia.io 5 points 4 months ago

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.

[-] Hawke@lemmy.world 2 points 4 months ago

Pretty sure that’s mostly a retcon and it’s actually just plot armor preventing the stormtroopers from aiming.

[-] FaceDeer@fedia.io 3 points 4 months ago

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.

Dude I was about to say, there's no way they don't have a quicker way to track calls. They just wouldn't tell us for obvious reasons.

I'll say for your comment on slugs, we used 10 gauge Magnum slugs and had no issue on reinforced doors or padlocks. A bit scary, but fun and informative.

I'm here to learn how many of these truths are actually just myths of their own!

[-] Plopp@lemmy.world 26 points 4 months ago

A stopped heart can actually be started with bullets fired from two guns with silencers.

[-] Empricorn@feddit.nl 11 points 4 months ago

That's only true if you're both skydiving.

[-] norimee@lemmy.world 31 points 4 months ago

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.

Source: nurse am I.

[-] conditional_soup@lemm.ee 10 points 4 months ago

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".

[-] Theharpyeagle@lemmy.world 4 points 4 months ago* (last edited 4 months ago)

For some reason it never occurred to me that chest compressions were actually to help pump blood. I guess I assumed it was just some magic that might start a heart up again.

[-] norimee@lemmy.world 4 points 4 months ago

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.

I'm glad you know now. Maybe you'll save someone's life with that knowledge now.

[-] Empricorn@feddit.nl 29 points 4 months ago

What a dumb, inconsistent list.

[-] MystikIncarnate@lemmy.ca 4 points 4 months ago

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.

Asteroids in a belt have a large distance between them, but I'd imagine rubble from a planet or moon recently destroyed by the empire would probably be grouped a lot more tightly.

Some grenades can have their pins pulled with teeth, but it's a dumb idea.

[-] echodot@feddit.uk 6 points 4 months ago

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.

This is probably what happened with the ice moon of Europa.

[-] AngryCommieKender@lemmy.world 3 points 4 months ago

It's also probably what happened to Earth when Theia hit us, and we gained our Moon(s)

The asteroid field in Empire Strikes Back, the one most prominent in pop culture, was not from a recently destroyed planet.

Some fire extinguishers have pins that can be pulled with your teeth, some don't. Doesn't make it a "myth"...

The drowning one doesn't only apply to drowning but a lot of medical emergencies. People in need are often embarrassed to ask for help. Some are to busy panicking so they cometely freeze up. If someone acts odd just ask if they are alright.

people can easily shatter padlock shackles with ramsets, which are basically little blank round gunpowder powered hammers. not sure if a gun would, but sure seems like it.

also, the asteroid one is probably quite true, but saturns ring are between 10m and 1 km in thickness, so there are exceptions.

[-] CheeseNoodle@lemmy.world 5 points 4 months ago

Mythbusters were able to easily break all but the largest padlocks with a hammer so you could probably pistol whip a lot of them too.

[-] EddyNottingham@lemmy.ml 4 points 4 months ago

The Slowmo Guys released a video on YouTube recently where they shot a pistol at a padlock not really expecting it to break, but it did, haha! I think it took a few rounds though.

[-] AhismaMiasma@lemm.ee 5 points 4 months ago

Like half of these are TV shows. House MD, X Files, Baywatch just at a glance.

  • Shooting two guns at the same time looks cool.
  • Aiming at two targets at the same time is hardly possible.

These are not in any way mutually exclusive and in fact are both true.

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.

[-] shalafi@lemmy.world 4 points 4 months ago

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.

Watch some videos of people going down. They exhibit very similar behaviors. If you're a parent, this is required watching.

Plenty more out there, but what is described is exactly how I went down. And I was 20-yards from a certified life guard in an old cow pond.
