Not sure if this is in the correct place...

BIL is in custody right now for a crime he and some others committed, he has an upcoming court date and i want to go to support him but i am at a crossroads as i in no way support his actions.

Ordinarily he has been a pretty decent kid, typical teenage male but all in all a good kid, we get on great, he loves his nieces, DP and I have no idea what caused him to do what he did..

How do i support him without it seeming like i condone what he did...
