In criminal law, stealing is called theft.
In estate law, looting is called a fiduciary failure; a breach of trust.
The weird language of fiduciary law comes from King Henry VIII's language, with roots in English chancery law, which was used to disguise from the common folk what was really going on among the powerful and the privileged.
Theft from an estate is sanitized by calling it self-dealing, breach of fiduciary duty, conversion, unjust enrichment, breach of trust,where administrators help themselves to estate property.
