An editorial interpretation.
The speaker threatens violence if another visit becomes necessary. The condition makes his return itself a warning, pressing the listeners to prevent it. The blunt image of cracking skulls supplies intimidation, while the quotation leaves the specific behavior being demanded unstated.
