Maybe a nitpick, but I think it would be more accurate to say that it has, in recent years,
become policy to not confront thieves,
even verbally and non-violently because so many of them are now willing to escalate to lethal force on the most trivial of provocations, effectively giving them a heckler's veto[1] on any measure except locking them up or asking the police if they'll find time to arrest.
I know in my grocery store training c. 1998 they definitely told us to give verbal warnings to thieves that we saw what they did, but now, even that much is dangerous.
>Insurance covers material losses as long as reasonable precautions are taken.
No one would get insurance to cover small, regular losses. And even so, insurance isn't some magic pot of gold that restores the losses that lead to closure, it just means the impact is absorbed over everyone. It's still there.
