Rules for Posting Guides on Our Community
1. Defining a Guide Guides are comprehensive reference materials, how-tos, or comparison tables. A guide must be well-organized both in content and layout. Information should be easily accessible without unnecessary navigation. Guides can include flowcharts, step-by-step instructions, or visual references that compare different elements side by side.
2. Infographic Guidelines Infographics are permitted if they are educational and informative. They should aim to convey complex information visually and clearly. However, infographics that primarily serve as visual essays without structured guidance will be subject to removal.
3. Grey Area Moderators may use discretion when deciding to remove posts. If in doubt, message us or use downvotes for content you find inappropriate.
4. Source Attribution If you know the original source of a guide, share it in the comments to credit the creators.
5. Diverse Content To keep our community engaging, avoid saturating the feed with similar topics. Excessive posts on a single topic may be moderated to maintain diversity.
6. Verify in Comments Always check the comments for additional insights or corrections. Moderators rely on community expertise for accuracy.

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.
It's worth noting that nearly none of the people you see testing suppressors online use a pistol with a slide that is locked so it doesn't cycle, shooting through a suppressor that has the right type of "lube" applied, with rubber wipes at the very end to let the bullet through then reseal the suppressor for a few shots, before they're completely shot out.
You don't get a lot of silent shots, and you've got to rack the slide yourself for each of them, but they do get quite a bit quieter than the suppressor mythbusters think they do, running their dry, open suppressors in semi auto.
