Good news/bad news about dealing with contractors

So, we've been trying to get the electrician to show up with the wire inspector to get his work inspected for the past month and a half. Literally. It's been six weeks since the electrician finished his work, and nothing else can be done until the work is inspected.

Finally, today, the electrician deigned to show up with the wire inspector.

That's the good news.

Then there's the bad news.

None of his work passed inspection.

At what point is homicide considered not only justifiable, but morally imperative?
