Abstract

Methods and systems are provided for determining inconsistencies between two or more sets of characteristics relating to an accident. In an embodiment, sets of characteristics relating to an accident may be used to determine liability in the accident. The at least one of the sets of characteristics may be determined from witness statements. The at least one set of characteristics determined from witness statements may be compare to other sets of characteristics determined from witness statements or to other sets of characteristics determined in other ways. The comparison may determine if there are inconsistencies in the sets of characteristics.
