No, “vetting” basically means they checked to see if you ever got caught embezzling money, or in the case of clearances, if you lied about committing any crimes (committing them is ok). They are regular people and getting them to abide by sensible IT policies is a giant nightmare and compliance is poor.
Heck, have people already forgotten Trump’s tax returns were leaked by politically motivated “vetted” people working for the IRS? Not the first time that happened either. And they didn’t even find anything interesting!
