Slow down -- sometimes. But for the most part, locks are more like envelopes. They produce evidence of tampering.

Which is why McNally (the youtube in the title) demonstrating poor locks that can be opened by simple bypass attacks like shimming or whacking is especially damning for those locks. You can always destroy a lock with brute force, preferably power tools. You also spend years honing your lock-picking skills and open any keyed lock in less than a minute, but good locks make this a difficult craft. But shimming a padlock or whacking a masterlock with another masterlock takes no skill, doesn't leave evidence and allows you to relock it when you are done. It defeats every protection the lock was supposed to provide

Yep. There’s a safe engineer on YouTube who was explaining the history of dial combination locks commonly used for government filing cabinets, etc. He pointed out that you can drill them in minutes but you’d need several hours to make good the damage such that the break in wouldn’t be easily detected. The combined time is therefore the ‘strength’ of the security. (Also, why it might be a good idea to have open sensors on safes, cabinets, etc)

Not sure if you're referring to DeviantOllam or someone else, but here is his awesome talk on safes: https://www.youtube.com/watch?v=-Z_Jv7vuiqg

He is a great source of knowledge on physical security for laymen and professionals alike, and leaves an impression of an extremely amicable and well-rounded human being.

That's why one of the more advanced challenges in lock picking is to minimize the amount of evidence you leave. Eg even a normal pick can leave some scratches on and in the lock in different places than a normal key.

If I remember right, 'bumping' is an interesting technique partially because it leaves even less of a trace.

Yup, I've got a three bolt break in resistant front door in my house, but right next to it is a window that can be breached in .5 seconds by yeeting a brick though it. But both will leave traces if they've been forced so my home owner's insurance should cover any losses / damages.

That seems to be a rather weak security, especially relying on “…should cover…” to save you, which I presume you have also never been able to test. And that’s without addressing common mistakes like not realizing the policy is for cash value and requires evidence; which people do not have, is not updated, or is not compliant. That can leave people with effectively no coverage at all, with the only test being run in deployed systems… the first time you check if your arms supplier provided quality arms, is when you’re facing the enemy trying to kill your at the front lines.

"Having windows in your home is weak security": The trade-off between usability and security incarnate.

Some windows are more resilient than others.

When I lived in a less than stellar neighbourhood in Germany, we had windows that you couldn't throw a brick through. (Some tougher than usual glass.)

No. You can get security glass. There’s no trade off.

You’re right, they should board up all their windows or live in a concrete box.

Ever heard of security glass? No need to be snarky and unlikable.

You are so confidently stating this as if you mentioned that at all in your previous post lol - obviously that’s not the issue I had with your comment. Sure, I was a little snarky, but you started it with your bad attitude.
