We don't necessarily need to jail the clown who did this, but we DO need to jail the head clown.
I've never seen a good electrician volunteer to do something wrong just for the heck of it, but I've seen a lot of competent folks do junk like this because they were afraid of being fired if they told the boss "NO".
I always liked the philosophy that the highest ranking guy in the chain is held completely responsible; if that means dye in the river, wire around a fuse, or stale candy in the vending machine.
It's too easy for the head clown to intimidate folks into doing something dangerous or stupid by threatening their job; especially if there is nothing that makes the boss ultimately responsible.
