Agreed - different times or not, the movie Home Alone is still rated PG (didn’t the kid have access to a BB gun in one of them - rendering it an accessible household item to have around in a popular family movie)? I’m not saying this was acceptable behavior - just that it was likely intended as a dumb prank and nothing more. Yes - someone can absolutely get hurt by horsing around with one, but kids throw rocks and sticks in the park all the time too and someone at the wrong place and time could also get very hurt from those items.
Unfortunately, NJ law says otherwise (this calls for mandatory jail time vs the DUI) so that may come into play on the outcome here.
