So instead of trying to cover every possible theoretical danger, setting clear rules and boundaries with your kid sounds like a way more sensible and pragmatic approach.
And nobody said kids should be punished or held fully accountable on their first mistake.
Trying to scare children into following rules does not and will not end well.
> I've seen this done, it works.
You think it works because the child has realized that they will need to be better at hiding their actions in the future.
I believe in discipline but smashing a device violently in front of a child is not the way to go about things.
Anyway I tend to agree for the most part anyway. I was just making a guess about your age irl based on what you said. However some other data actually indicates you are likely gen-x.
