Essentially everyone has stolen at some point in their lives, and almost everyone has gone into private property they theoretically shouldn't have gone into. My door has a lock, but must adults could get in by kicking it a few times with determination. That's true of most locks in existence. They're there to stop people who don't actually want to cause any real damage.

> Essentially everyone has stolen at some point in their lives Isn't this a fairly wild claim? I've never stolen anything and can't imagine doing so. That's a pretty dismal view of the human race isn't it.

You complained about the theft claim, but not the trespassing claim, so it seems I still need that lock to keep you from wandering in.

You probably have stolen something, even if it's just a failure to return a book you borrowed from someone, or office supplies that wandered off with you (pens vanish like you wouldn't belive).

I (and I assumed everyone with a dead bolt) only ever lock the dead bolt. What's the point of locking the door handle if there is a dead bolt?

I mean, it’s there; you might as well.

Deadbolt only guy here too.

You could have a magnetic switch somewhere that you could tap SOS on with a magnet or something. Or just knock on the door with a certain pattern. Or speak "Open the pod bay doors, Hal" into a pinhole mike. I'm sure you could think of many methods.

And when your house has no power?

Battery backups, of course.

There will always be failure modes. I mean, the failure mode for a traditional lock is "I lost my keys". Unless you have someone else with a spare set who can get to your location in a time you deem reasonable, you're going to have to have the door forced.

Yes. The truth is most (and I mean nearly all) residential door frames snap like a match stick with a hooligan tool. In a previous life I kicked in doors for a living. I don’t give a fuck how cool your dead bolt is. I could be in your face before you were out of bed. If you want to keep out lazy thieves any lock will do. If you’re preventing against a dynamic entry you need trip wires, man traps, metal door frames, a…

Metal door frames here. No comment on the others.

I broke a window with a pebble when I was a kid. Most people have windows. Something like an extra sticky vinyl sticker takes care of the noise problem.

> Isn't the point of a lock just to keep honest people honest? No. Honest people don't need to be "kept honest". Locks have the same purpose as other security systems (including electronic ones like crypto, etc.). They aren't intended to (and can't) keep a determined attacker out. What they do is increase the cost (in terms of time, effort, risk, etc.) of gaining access. The point is -- as far as possible -- to make…

Freaking American's and their "inward opening doors". Good luck kicking in any door in civilized countries in which doors open outwards.

That wouldn't work on a double glazed window.

I once had a storage unit, and lost the key to the padlock. The manager said "no problem", and we went out to the unit. The manager pulled out a battery operated angle grinder, and cut the lock off in about 5 seconds.

You're going to need a bank vault to beat an angle grinder. Those tools are the shiznit.

Slightly related to this, the Lock Picking Lawyer on Youtube has number of videos where he tries a Ramset gun [1] against different padlocks. For example: https://youtu.be/Wimo09WV-rY This was interesting as it was an attack that certainly would not have crossed my mind. Would be interesting to see how other types of locks would do against this kind of tool. [1] https://www.homedepot.com/p/Ramset-MasterShot-0-22-Cali…

Thanks for an LPL reference!

Speaking of "smartlocks": here’s one that doesn’t even need a drill: https://www.youtube.com/watch?v=WeCGTosv-_c

I don’t think they’re suggesting that everyone on earth has purposefully become a thief at one point, but that sometimes it just happens. I’ve definitely walked out of a supermarket with a bottle of water that I picked up while shopping and forgot to pay for - I still stole it, even if unintentionally.

How often do you unintentionally walk into someone’s unlocked house and steal something, though?

In the Canadian North, it's traditional to leave your summer cabin unlocked over the winter so that if someone is lost in the woods they can come in and warm up. It wasn't unusual to come back find that someone had used it over the winter.

Security isn't about preventing someone from breaching the "lock". It's the level of difficulty (measured in time) that it takes to breach the "lock". That being said, given unlimited resources; no lock is unbreachable.

Yes. But a difficulty of 4 seconds is a bit too low. I expect 30-60 seconds for an door with moderate security.
