The FARs are not "normal" law in the US. The are "administrative law", which leaves the government wide latitude in how they interpret and apply the regs.

I don't think they are using the criminal thing as a basis to disqualify you, but rather a basis to further investigate your medical history (specifically mental health). I'm sure the circumstances you describe will not be a big deal.
