    I see we’re still sharing this guide of misinformation.

    You can aim at two targets. Phone tracing does not take an hour. You can shoot and disable most locks including the one pictured with most calibers that aren’t a .22. Grenade pins can be pulled with teeth depending on grenade and whether you’re applying tension to the spoon. Gunshot noise is affected by a suppressor, but bullet noise is based on speed, weight, and shape.

      • You can report people before 24h have passed but the cops may still want you to wait. They do this because they’re lazy/don’t want to waste time dealing with paranoid folk.
      • A gun can be completely silenced when built to do so. Generally using subsonic ammunition and not semi-auto.

        Yeah, just pointing out that a suppressor doesn’t affect the bullet sound. If it’s supersonic, it will still crack.

        The can just gives the explosion (gunshot) time to expand and slow down. I am intimately familiar with this concept and have a nearly silent build myself.

        Edit: sidenote, if you want to shave off a few more decibels from the noise of the shot, add a small amount of material to ablate inside the suppressor. A VERY small amount of water will do in a pinch but petroleum gels are better. I personally recommend a cleaner gel like medical ultrasound gel, very clean and very effective.

      To be fair they said “aiming two guns at once is hardly possible”. Means it is with enough practice? Lol. I hate this guide, full of half-truths and misinfo, not to mention completely withholding explanations.

      Ok, I know nothing about grenades but from what I’ve seen I imagine there’s a spring mechanism and that is clamping the pin down. So wouldn’t pressing down on the clamp make pulling the pin easy/easier?

        Ya, most grenades have a lever called a “spoon” that you press down that relieves some of the tension on the pin, and when you pull the pin and throw the grenade the spoon flies off and ignites the fuse.

      They’re probably referring to the confidence clip. We used to tape the spoon to the grenade because if the pin got caught on your jacket, you’d have a really bad day. There’s actually an extra step before you pull the pin where you sweep your thumb across the spoon to allow the pin to be pulled out. If you just grabbed a grenade and tried to rip the pin out with your teeth, without removing the confidence clip, you’d rip your teeth out.

          You wouldn’t have remembered if it was 20 years ago. That clip was introduced recently, I remember where I was the first time I saw one and that would’ve been like 2015.

            Hmm, they definitely had safety clips back then, I just double checked. So might be a different design, but same concept. I just looked at the m67 Wikipedia page and that looks like what I’ve used.

    The phone tracing one is misleading. It might take hours for the police to get the location from the ISP (I doubt that), but the phone call doesn’t have to be hours long.

      It takes typing a single command to trace a call.

      What takes time is getting the authorization to the person who has the password permission to issue that command.

      Very few people at the phone company are allowed access to those commands.

    The Defibrillator thing is very misleading. Yes, a Defibrillator alone cannot restart a heart. You need to do CPR and if you can combine it with a Defibrillator (operated by a doctor or an AED) you actually have a chance of reviving someone (obviously there is no 100% success rate and the person needs to be “freshly” dead).

      Well but a defibulator isn’t used to restart a stopped heart. You only shock for Vtac or Vfib. When in doubt, turn it on, put the pads on and the machine will say ‘shock suggested’. If not just do CPR.

      Yeah but this is referencing the movie trope where the person has a fully stopped heart and they shock it back to life. In reality applying cpr is just keeping the blood pumping to supply the brain with oxygen in the hope the body restarts the heart itself. That’s why modern defib machines check the nerve impulses to see if shocking it would help. Of there is no heartbeat, it won’t help and will refuse to shock. Once the body restarts the heart but the rhythm isn’t correct shocking can help. The shocks also aren’t huge shocks where the person violently lurches up and putting in more energy won’t help either. The machine checks the rhythm and applies a series of shocks to help the nerves regain their normal pattern and thus tell the heart to pump in the right sequence and speed. Just randomly zapping will probably do more harm than good.

      It’s pretty nice the emergency defib machines we have all over the place these days are smart enough to help without needing to know how it does their thing. Because 80s and 90s TV and movies have muddied the water quite a bit.

      The movies usually show an asystole being defibrillated and that is not done. To the best of my very limited medical knowledge you first need to use CPR and medication to get some electric activity from the heart to defibrillate.

    I’m very confused on the grenade pin one.

    If you held down the level (not sure what it’s called), wouldn’t the pin be fairly easy to remove? Why would that be harder than your teeth?

    I’ve never seen a grenade in person.

      Yes, you hold down the spoon and almost all of the tension gets removed from the pin, it’s made to be easily pulled with one finger by anybody.

      If you’re holding the spoon, you can pull the pin.

      Check out my other comment but I’m pretty sure it’s because of the confidence clip. There’s actually an extra step where you sweep your thumb across the spoon to allow the pin to be removed from the grenade. After that yeah you probably could pull it with your teeth… but if you fucked up and fumbled it you’d win the Darwin award.

      Really the myth should be about cooking a grenade. Absolutely no way in fucking hell you’d ever trust that fuse to “actually” be 4 seconds. What if it’s short and actually 3? And you wait to 2 to throw? Nooo way lmao

    I hear the silencer one a lot, and although it’s not nearly as quiet as media likes to suggest, they can be much quieter than you expect. There are a lot of variables to play with when it comes to guns and noise.

      My neighbor at camp handed me his silenced .22 loaded with subsonic ammo. All I could hear was the action moving back and forth. So clear, I realized I had heard that exact sound because I have the same gun in a different form!

      OTOH, it’s impossible to get a significantly silent supersonic round down to “quiet”, not even close. And none y’all better steal my new band name!

      Shame most Americans take the term “silencer” literally. We’ll never see sane legislation. Meanwhile, in Europe, I’m told some ranges mandate suppressors, and at best, you’re considered a douche canoe blasting away without one.

      Going to bite the bullet (heh) and get one on my AR when I can afford (and have time to figure out the tiresome paperwork and fees). The noise is stunning and I’d like to be more considerate of my country neighbors.

      Shooting two guns at the same time sucks whether it is at one or multiple targets.

      You can’t look down the sights on both at the same time, and the recoil is goofy because you can’t line both up with your body if aiming at the same target. So you are either shooting one blindly or two awkwardly.

            I don’t remember exactly because last time I saw the Matrix was two decades ago but i had the impression that Neo didn’t shoot exactly at the same time but alternating, although at superhuman speeds

            Edit: yes the handguns were shot alternately https://yewtu.be/watch?v=Z2eCmhBgsyI (at around 1:10), but automatic rifles and uzis were shot at the same time

    It’s not a myth that shooting two guns at once looks cool. It looks super cool. Accuracy has nothing to do with how cool it looks.

    Padlock shackles haven’t been made of iron for around 120 years. They’re made of case-hardened steel.

    I’m pretty sure you can hear someone who is yelling while skydiving, because my friend has a video of him skydiving and you can hear him yelling in the video. Camera microphones are usually worse at picking up sounds in heavy winds than human ears are.

    Some of the others seem suspicious too, but I’m not sure enough to dispute.

    The grenade thing depends on the generation of grenade. Also depends on the country of origin. Assuming we are talking about the American M67 one you see in most movies, there are 3 different generations of safeties.

    Quick basics of an American grenade- the spoon is the handle looking thing that is sticking out the top and runs along the side. Under it in the head of the grenade is a spring that is always trying to push the spoon off its hinge and make it fly off, while then starting the fuse and the whole bang process. The safety pin (a codder pin with a ring on one side to pull on) runs through the head of the spoon and is held in place simply through binding into its hole/channel by tension provided by the spring. For a little bit of extra safety the end of the pin sticks out about a quarter inch and is bent for a little, but easily straightened and pulled out with the ring (look up a picture and you will see what mean).

    The old ones were just the safety pin held in place by the spring/spoon mechanism. But if you had excessive vibration or just enough pressure and you had pre-straightened the safety for pulling ease, it would negate the spring pressure and the safety pin could slip in and out with ease (thus easy to pull with teeth for Rambo effect). People didn’t trust it, so it was typical to then use electrical tape to hold the spoon down wrapped around the full body and then a bit extra folded back to make a quick pull tab. To throw: pull e-tape, pull pin, throw. The army then added a secondary safety to the safety. It was this secondary safety clip that held the spoon down to the head, providing constant tension and stopping the vibration loosening issues. They were also intentionally designed to have to get pulled off in opposite directions. To throw: (I am left handed) sweep safety clip left, pull pin right, throw. This was in my opinion the best setup and my favorite of grenade generations. Apparently this was about 50/50 with other others. So the army then came out with their third generation, the “confidence” thumb guard thing. It is a metal flap switch that locks/latches the safety clip onto the pin ring. I thought it was dumb. Most people hate it. But credit where credit due- it is impossible to fuck it up. Now to throw: thumb/sweep up on confidence latch, sweep left on safety clip, pull right on pin, throw.

    Waiting 24 hours to report a person missing isn’t a myth… just a stupid fucking thing that happens a lot and has no basis in law.

    You could try to report a person missing immediately but depending on their age, gender, sex, sexual orientation, race, ethnicity, economic status, job employment, location, and maybe many more factors, a police/sheriff department might flat out deny a report because they simply can’t do their job right.

    It’s not a myth; it is reality and many people encounter this issue. Especially in the ‘70s and ‘80s in the United States, teenagers would often be dismissed as missing and considered runaways. So the fact is you might be forced to wait or have your report completely ignored by the appropriate law enforcement agency.
