dépiauter

Colloquially, to skin an animal (dépiauter un lapin) or strip something of its outer covering — and, just as commonly in figurative use, to dissect or pick apart something in minute detail (dépiauter un dossier, un contrat).

• Le chasseur a dépiauté le lapin avant de le cuisiner. — The hunter skinned the rabbit before cooking it.
• Les journalistes ont dépiauté le rapport ligne par ligne. — The journalists picked apart the report line by line.
• Il a dépiauté le contrat pour en comprendre chaque clause. — He dissected the contract to understand every clause.

The figurative sense (analyzing something in painstaking detail) is at least as common in journalism and everyday speech as the literal skinning sense — don't assume it's only a hunting/cooking word.
