If the liquor store owner knows that some of those bottles might contain pure methanol, and people end up dying from drinking said methanol...then, yes, I do think the store owner should do some serious jailtime.

Which is what this boils down to. Ross didn't know what people were selling. Could be pure high-quality stuff, could be contaminated stuff, could be stuff that was cut up with fent. He made money either way.

Why not incarcerate all car makers and doctors then too?

You are hopelessly lost my friend, unable to comprehend the concept of illegal activity.

The comment you replied to referenced "multiple teenagers" - the very people that liquor stores cannot sell alcohol to since they're not recognized as mature enough to be freely allowed to drink.

SR allowed children to buy addictive poison without any regulation whatsoever, and Ross profited off of those transactions.

These are not comparable institutions.

The law recognizes that a bottle of beer generally cannot be used to murder someone else.

Charles Manson never murdered anyone. Should his sentence been commuted?
