Best thing is that the guns are registered, and he had the Ohio permit. I think This would lead prosecutors to remove the felony charges until he gets the permit paperwork corrected. Unless the prosecutors believe he was in the wrong place, doing no good, then they could get the permit rescinded for the THC possession and use and ask for more stringent charges..
Most of them knew: why, and what they were getting, to be there; and were compensated financially. Was there any non consenting rape claims in the trials or was it all statutory? I hope that question is not victim blaming.
Its a felony but the permit in Ohio may lead to a plea deal. unless the THC possession voids the Ohio permit. Theres a drug use question on almost all permit forms.
