in that case, the problem isn’t with selling an item... but the out of control legal system that has been setting the ground work for such legislation.
a short time after the sale, the seller should be able to completely wash their hands of any responsibility.
how someone uses the product you sold them is not your concern. if it were, even selling a soda can to a potential criminal would make you liable (as you can easily beat someone to death w/ a few soda cans)
Only leftards think we should have greater background checks when we exercise our constitutional rights, but that it’s a crime to ask if someone is in our nation illegally.
