N.J. Stat. § 2A:48-1
When, by reason of a mob or riot, any property, real or personal, is destroyed or injured, the municipality if it has a paid police force, in which the mob congregates or riot occurs, or, if not in such a municipality, the county in which such property is or was situate, shall be liable to the person whose property was so destroyed or injured for the damages sustained thereby, recoverable in an action by or in behalf of such person, in an amount not to exceed $10,000.00 for the aggregate of damage done to all such property, both real and personal, at each separate location within a municipality; provided, however, that no person, and no subrogee of such person, having insurance coverage in whole or in part for the said destruction or injury, shall have a cause of action against such municipality or county at common law or pursuant to the provisions of this act. For the purpose of this section, insurance coverage means insurance obtained through any source whatsoever, including insurance purchased through any insurance pool, placement facility, plan of operation, or any other plan established pursuant to Federal or State law.
