I don't know why you got downvoted. What you said is true. I've walked right up and asked police officers if they'd bother with someone smoking pot out in public. Just to prove a point to friends. Most say that it's illegal but they're not encouraged to go after these people. It's not even worth the paperwork. "Ohh you got me and my half smoked blunt. Way to go Columbo."

In my world. People like this are locked in pillories, forever.
