Unless I miss my guess, I doubt there are any gun restrictions on the books in Arkansas subject to challenge under yesterday's U.S. Supreme Court ruling. The legislature took away city and county home rule on gun legislation years ago.
But for gun nuts and their opposite number, there's good analysis in the NY Times of what will come next. The court's care to say many kinds of restrictions, including on specific weapons, would not be disturbed doesn't mean the NRA won't be out trying to blow holes in any impediment to quick arming of the populace with as many and as powerful guns as possible. Linda Greenhouse did her usual good reporting of the decision itself.
