Examples exist where the crucified are buried in tombs (in AD 30, Jerusalem).1 This is relevant because it entails Romans did allow Jews to bury the crucified.
Romans accommodated Jewish law/demands during peacetime (AD 30).
• …Against Apion 2.73
• …Wars of the Jews 2.20, see 2.289-92, 6.334]; cf. also 6:101.)
• …Antiquities of the Jews 16:160-173
• …Philo reports it in Embassy to Gaius 299-300.
Jews wouldn't have requested crucifixion unless burial after was guaranteed.1 This is relevant because crucifixion was requested by the Jews.2
Romans hastened the crucified's death on behalf of the Jews.1 This is relevant because the Romans did this for the Jews, knowing their intent to bury.
There are well-attested instances of mass crucifixion wherein the crucified were not permitted burial.
So? These were “in times of acute crisis.”1
