Good. As it stands right now, pot possession under 25g is a violation, whereas publicly "displaying" the same amount of mj is arrestable. So the NYPD forces people to empty their pockets during stop-and-frisks, and then arrests them for "displaying" a joint.
Cuomo is hoping to cut down on this abuse by changing public display to a violation. Should be amusing to read the comments of certain cop-hugging bridge-and-tunnelers on this thread

I'm normally for local autonomy, but if the state slaps NYC and the NYPD down, this will be a good thing.
