I haven't kept up with the Rittenhouse case (not from the US), but it seems to me like the kid was committing a crime by even having a firearm in the first place, let alone deciding that he's going to take on a job for which he has no experience or training, and he willingly put himself in an extremely stupid and entirely avoidable situation that resulted in the death of two people. What's so complicated? Throw the book at him, IMO. He's clearly a peanut-brained idiot with a Rambo fixation who needs to be taught a lesson and as an example to any other dickheads out there with similar fantasies.
