Fisherman. This goes way beyond mere 'imperfection,' or 'screwing up,' as you put it.
Suppose your kid's school administrator hires a gym teacher, knowing FULL-WELL that this individual has a criminal conviction for kiddy-porn. Suppose that same gym teacher sexually molests YOUR child in the locker room when no one was around.
I guess you'd just shrug your shoulders and say, "well, the administration just 'screwed' up. They're 'imperfect.'" Right? Is that what you'd do? If so, then you disgust me.
And as for not trusting others with the 'little ones,' are you telling me that you attend school with your kids?
