It's immoral because he is breaking the law. War on drugs is a failure because theres people like you pushing it down. On a side note brother, whats your religion?
My religion? None. My philosophical viewpoint would be rationalist.
Your assertion is that anything legal is therefore moral. So if congress passed a law stating that it is required to kill babies, would that therefore be moral according to your standard?
You are also asserting that the drug war is a failure because people oppose it. I never stated why it was a failure, simply stating the fact that it is. When public policy is a failure it needs to be revised, no matter the cause of those failings.
