I can't think of any banned and confiscated vehicles
On further look you are correct, none were banned and confiscated.... However they were pulled from production by the manufacturer so as not to lose revenue, or be susceptible to a class action suit.
My opinion is that (specifically regarding) the AR-15 manufacturers do not pull the weapon because 1) it's an admittance of sorts of the weapon being an issue (a low but potential probability) and 2) They don't want to lose earnings (the highest of probabilities).... They know their (seriously no pun intended) target demographic, the weapon is so hot button, that every time a event arises, and the "ban this weapon" gets stated, the AR/2A supporters go out and buy more of them. The manufacturer has no desire to find solutions to a possible "epidemic", they (as I suppose all corporations, from weapons, opiate pharm companies, and the guy who allowed those hoverboards that knowingly caught on fire) are only interested in earnings and keeping shareholders happy.
Like I said, if everyone were just transparent and honest...
AR supporters- The gun is fun to shoot, no practical hunting or protection need for it, it's just fucking fun.
Manufacturers/Gun Shops- It makes us BANK
Politicians- We get money from the Manufacturer. The more they sell, the more we get, so EVERYONE can have one.
All honesty, all transparency, all logic.
