There is an idiom in English, “you don’t let the foxes guard the hen house.” I’m not sure how well it translates, but the meaning is simple – don't have people or things who can’t necessarily be trusted to do things requiring trust.

Own it. Period. We can go home now.  What’s that?   Group risk and security won’t let you monitor a real account?   Then give up, you’ve failed before you’ve even [...]
