There is nobody to enforce it. The police have more important things to do.
It may wind up somewhat unenforced, but it's still an ordinance on the books. To be fully enforceable, the City of Los Angeles will have to put surveillance cameras in every toilet stall in every "public building" in the city, and then hire people (ex-TSA maybe?, foreign terrorists maybe?) to monitor those cameras. Joking aside, the minions of public safety can always use it as an extra "gotcha" if you're arrested for anything else.
How much money do they take in on cigarettes ?
That's part of why this nonsense passed. Truth be told, no city can effectively tax
vaping: vapers will simply acquire their stuff outside city limits. And if you take as true the proposition that the alderoids have attained an emotional maturity equal to or less than their shoe sizes, then this is an example of "if we can't tax it, you can't do it — niener niener, nyah nyah."
Was there ever an opportunity to
vaping Community to protest or make case against this?
Yes, there was. Please, people, let's pay more attention to the "Legislation News" and "CASAA" forums on this website.
