Working in security and doing security door/door access installs with a locksmith and getting into locksport, I've noticed- and maybe it's just a thing local to me- that like 95% of the doors in the world are not installed correctly. Holy shit you guys.
Maybe @deviantollam or @alice can corroborate or deny this being their experience but I'll just walk around town with my wife and be like "Ope, that gap is way too big, I could get in like this" or "Wow, that's not aligned right and they didn't put the strike plate on" the ENTIRE time

@brad it's true. Most locksmiths and door installers use oversized strike plates because it's easier than fitting them correctly, and customers don't like it when their structure settles and then the door doesn't close properly, so you'd be surprised how many doors don't engage the deadlatch.

@deviantollam

@alice @brad @deviantollam I'd always assumed incompetence before but your explanation makes much more sense: it's the classic cost+convenience vs security trade-off. Less security = less callbacks.

@riskythinking @deviantollam @alice @brad Good to know that it's not just cybersecurity that works this way.

Like when the heaviest encryption can be defeated by knowing the answer to "what's your mother's maiden name?"

@me

Although I know my mother's maiden name, I need a password manager to remember my "mother's maiden name" for every login.

@deviantollam @alice @riskythinking @brad

@alice @brad absolute agree

@deviantollam I think I actually learned that bit of trivia from you πŸ˜‹

I have a stop on my route that got broken into through their roll up door windows. they installed an electronic alarm system. then 2 weeks later when I tried to leave the front door wouldn't latch. the strike plate had been shimmed closer to the door latch badly and it required multiple slammings to get it to latch. πŸ€·β€β™‚οΈ

@coolcalmcollected @alice @deviantollam My wife's print studio just had a guy install a commercial double door and put the surface latch on the wrong side of the door- It doesn't lock anything and its accessible from the outside ΰ² _ΰ² 
@coolcalmcollected @alice @deviantollam Don't worry, they also installed a second surface latch on the inside as well for what I'm sure are reasons. They marked the hole in the door frame for it to slide into but never cut the hole. We found out about this because the building manager was like "Hey, your door has been open for 3 days"

@alice Can’t tell if this is post is about locksport or infosec..

I’ve re-hung quite a few friends’ crappy Seattle area doors with long screws and full length plates. Your ring/cam and fancy WiFi lock don’t matter much IRL. Anti-kick does.

@brad @deviantollam

@badsamurai @alice @brad @deviantollam
Agreed. Long screws definitely make forced entry more difficult, and after an attempted break in damaged the door and jamb, I added steel plates with large screws into the middle of the stud.
@brad Most people don't know or understand the function of the deadlatch.
I built a crude model to explain it.

@brad - Yeah. Same with computer security.

"Locks keep honest people honest." is a saying for a reason. The facade of it being locked or secure is enough to prevent folks from making a mistake of convenience and trying to steal something because it looks easy.

But many things can be taken if you put in minimal effort.

Thank goodness most folks are either generally decent people or at the very least just can't be arsed to take whats not their's. (Society only works when this is the case...)

@brad true facts 😏πŸšͺ

@brad

the worst i've seen was a new subdivision where all the french doors were installed over a couple of days. they sent an junior person to do it. all were installed upside down, which made them non-functional. they had to redo all the doors (probably not much better but at least right side up).

@brad

Don't count on it, reminds me of the story of an airline pilot, he loved reading the papers (read them good and well) except about aviation where he always found errors.

Michael Crichton coined the term Gell-Mann Amnesia effect to describe forgetting how unreliable a source is in one area when you trust it in another area.

@ColinTheMathmo @hnapel Angela Collier also has an incredible video on this.
Also, if anything, I think I'm experiencing the opposite of that. Now that I am aware of how a door should work, I'm seeing how much nobody seems to do it correctly

@brad This is exactly the effect. Without specialist knowledge, things seem OK. Now that you *have* specialist knowledge, everything seems incompetent.

@ColinTheMathmo @hnapel Yeah I think I confused myself somewhere in there
@ColinTheMathmo @hnapel yeah, reading this back I truly have no idea what I was thinking there lol

@brad Yeah ... That happens.
