Some of these business just got plain old greedy and brought in a huge amount of inventory, likely at a significant discount because of volume. These same people were planning on enjoying a larger profit from each sale. I talked to a couple of store people and they told me that they only brought in a few gun that ended up on the "list" because they could see the writing on the wall.
So we all suffer because of the greed of a few!
^^^^this^^^^ I would add that they probably bought that inventory at a discount which would make their profits even greater - they bought and got burned a bad business decision = business loss. And, those dealers that bought on a line a credit it is like taking a cash advance on your CC and going to the Casino losing your money and then wanting the Casino to give you back your money.
