I’m no lawyer, nor have I read the entire law, but the simple point of this legislation- or at least, this type of legislation- is to reduce frivolous lawsuits and “law by litigation” concerning an otherwise-legal product.
And that’s the key- Love 'em or hate 'em, firearms are legal products to manufacture and sell, as long as all current State and Federal laws are observed.
The majority of the frivolous lawsuits have concerned alleged misuse- IE, somebody takes a gun and shoots somebody else with it. The suits have claimed the firearm is inherently dangerous, or doesn’t have adequate safety devices.
The problem is, the firearm worked as designed. Surprisingly few truly defective firearms reach the stores, and those that do are recalled so quickly it’ll make your head spin.
The manufacturer, however, cannot control who uses it, or who buys it, AFTER it has been otherwise legally sold to a licensed dealer, and the dealer has sold it to a valid buyer.
Many suits against the gun makers, if extended to, say, automobiles, would mean GM, Ford and Chrysler-Dodge would then be liable and responsible for things like drunk drivers, hit-and-runs, or plain old collisions.
Examples:
A) Ford makes F-150 truck, dealer buys truck, first owner buys it from dealer, buyer later sells to friend, friend then sells to some guy through the newspaper. Guy later gets plastered and mows down a group of nuns as they’re leaving the convent.
Is Ford responsible?
B) Smith & Wesson makes .357 revolver, dealer buys from S&W, first owner buys from dealer, owner sells to friend, friend sells to guy he doesn’t know, guy later holds up convenience store with it and shoots clerk.
Is S&W responsible?
Keep in mind the manufacturing and distribution of firearms is heavily regulated. Each and every unit is serial numbered (even factory test pieces, experimental units, and tooling dummies) and each and every one has to be tracked, tallied, and accounted for. Losing track of just one is reason enough for the BATFE to revoke a manufactrer’s license to make.
Manufacturers sell ONLY to properly licensed dealers- again, selling to anyone BUT said properly licensed dealer is reason enough to revoke licenses and impose extremely stiff fines.
Dealers are heavily regulated, their books are regularly checked, and they have to run an FBI check over the 'phone on each and every sale- again, if the paperwork is not in perfect order, if any sales are made without the NICS check, if a firearm is unaccounted for, severe penalties and fines await.
If you don’t pass the NICS, you don’t get the gun, period, end of story.
So in short, firearms are legal products, already heavily controlled, and manufactured and distributed in accordance with existing public law.
The suits claiming they are “defective” or “dangerous” are essentially frivolous, and are intended to cripple or bankrupt the manufacturers through litigation. Suits claiming the manufacturers did not “do enough” to keep the guns out of criminals’ hands are frivolous, because the manufacturer has zero control of the item after it has been sold- just as GM cannot control drunk drivers, and PC makers cannot control spammers or hackers.
I doubt the law was written to “immunize” the makers against actual design flaws or other factors for which they can be, and are, responsible. And being immune from violating laws? Get real- if the BATFE found out that Jerry’s Discount Gunmaker Company was selling rifles out the back door with no paperwork, law or no law the entire Justice department would have the place shut down before you can say Janet Reno.
Which is as it should be- believe it or not, even the NRA does NOT want firearms to be totally uncontrolled, or handed out free like Halloween candy.
As for exempting from H&S regs, that doesn’t mean that Smith & Wesson can remove all their handrails and take away all the workers’ safety glasses. It simply means they don’t have to plaster fifteen disclaimer notices or warning labels to each gun.
