Good info, including some surprises, like WY being on that list. Those of us covered by things like castle laws and no duty to retreat laws need to count our blessings.
Kudos to the store owner but the decision that he needed to keep an under-counter long-gun should be the indication it’s time to consider other measures. I’ve seen high-end watch and jewelry stores that have buzz-in systems so there must be a positive decision to allow somebody in the store.
I was surprised by WY and ND.
