The Talmud teaches:
The mouse is not the thief, but the hole.
Nevertheless, if there were no mouse,
how would the hole get filled with stolen goods?

In another rabbinic
passage,[2] the 3rd-century
Babylonian teacher, Rav, offers his students some protective advice
against the local, lurking thieves. We suspend judgment regarding
his stereotyping of his Babylonian neighbors.
