An end to butts in public spaces?

A motion is coming to the Board this Monday banning smoking in parks and on beaches in Vancouver. A noble idea and one that I support, but I do wonder how it will be enforced or more to the point, who will enforce it. We have plenty of by-laws in this city that are not enforced and I imagine this will just be another one. We don't have enough by-law officers to patrol our parks and public spaces as it is. In my local park most evenings you can find groups of people drinking alcohol and smoking dope, but no one stops them, despite calls to the Park Board and the police.It has been suggested that life-guards could enforce this by-law at the beach, but I think our life-guards time would be better spent watching the water not the sand. Although this is a good idea that sends a clear message, without the dollars to invest in enforcement it becomes yet another motion that says much but does little.
