Not to be picking holes in your coat, but a disreputable businessman would deliberately, not negligently, put the public in danger with his product. Why so I can't imagine, since it is a very bad business plan to kill all your customers.
...If some legitimately injured person wants to file suit, I can expose them to tremendous losses simply by hiring a lot of high-priced legal talent to defend myself.
If said businessman really did make a product that injured and/or killed those who use it you probably wouldn't be in business long enough to make any kind of war-chest you would need to cover legal costs.
Because if the Feds, your insurer, your lenders, etc. did pull the pull on you PDQ, the fact that your company has ZERO sales of your produce -- for who would buy it once it became know that your product scars/kills those who use it? -- would do the trick.
If I can spend $50,000 on lawyers, and expose the plaintiff to that kind of a loss, I can discourage an awful lot of legitimate claims.
In Cloud Cuckoo Land maybe, but not in the here-and-now. Besides, $50K on lawyers? That's it??
