NJ ruling on "possession"
Pdf here. One of Ev Nappen's cases, it concerns a juvenile who borrowed his grandfather's case, had a traffic stop, whereupon police found a rifle and some ammo in the trunk. Around here, it would be "nice rifle." In NJ, it's a year on juvenile probation.
The legally interesting point is that the appellate court finds there was no evidence of knowing "possession": at most, he knew of the ammo and/or gun at a point when there was no opportunity to get rid of it (short of leaving it on the sidewalk) before he was stopped.
