The person that sold him the drugs is not responsible for his death just as a gun dealer is not responsible if a gun he sells is used by a customer to commit suicide.
Another flawed analogy. The liberal-tarians are really slow today.
As before when I said motorcycles are legal, and not addictive. I have one. Selling guns is legal — dealers are licensed. Guns are not physically addictive. I have several.
There is a reason ILLEGAL drugs are ILLEGAL.
Surely you can come up with a better analogy — maybe even one that makes sense?
