Lets pretend there was no coronavirus and this was not hand sanitizer. Lets just assume that he was, in normal times, illegally selling any routine product on the black market.
Should he be charged? Arrested and his product confiscated? Of course. No question.
So now that the situation is so much worse. Far worse; why is anyone upset that authorities took the logical and prudent action that they did?
What’s logical and prudent about it. What’s illegal about selling a product on Amazon (or, as you call it, the black market). Folks can choose to buy or not. Nobody’s forcing them to do one or the other.
If the market runs out of .22 cal ammo and my neighbor has 500k rounds, can the ‘authorities’ raid his home?
What illegal selling?
If it is a routine, legal product, it is legal to sell it.
No black market for legal products.
“Lets just assume that he was, in normal times, illegally selling any routine product on the black market.”
They call that a flea market around here and the stuff isn’t illegal unless it’s stolen.
That’s a horrible analogy.
In the United States of America, there is no “Black Market” in goods purchased from retailers with appropriate taxes paid.
