For those unfamiliar it's worth learning about Blackstone's Ratio. Blackstone was extremely influential to the writers of the US constitution.

I think it should come natural to engineers because I see it as similar to failure engineering, but for the legal system. When you engineer a bridge, building, or even a program you build failure modes into them. Not to cause them to fail but to control fails. A simple version is "fail open" vs "fail closed". A bank safe that fails, fails closed. It is locked and you need to drill it open. Same with an encrypted harddrive but no drill... But a locked door in a public building will typically want to fail opened, least you trap people inside during a fire. A more complex example is the root of a conspiracy. When a tall building collapses you tend to want it to fall in on itself so it doesn't take out neighboring skyscrapers...

So Blackstone's Ratio (and Franklin's recounting) is similar. It asks "which mode of failure is better? That innocent man are condemned or that guilty men go free?" This is a question we must all ask ourselves least we back ourselves into a corner. There's no perfect solution. We don't want failure, we should reduce it as much as possible, but if/when it fails, which outcome do you prefer?

I'll link the wiki but the topic is so famous you'll find a million and I'm pretty sure it's taught in every law school in America
