It's a rare gathering that doesn't contain one person who would betray anyone for a half-year's pay. Judas was venal, but not unusually or unexpectedly so. If even Christ can't count on that kind of loyalty we can't either. Meaning that almost any organzation's security can be penetrated by pieces of silver, if the $5 wrench isn't practical. There aren't any state or corporate secrets or private data that we can depend on remaining that way, because the Judas-filter at human resources is reliably unreliable.
