alibis
(Other definitions for alibis that I've seen before include "Pleas of being elsewhere at the time of a crime" , "Proofs accused was elsewhere at time of crime" , "Defences of being elsewhere at the time of a crime" , "Legal defences of being somewhere else at times of crimes" , "Proofs of absence from the scene of the crime" .)
