So if people in NYC are already health conscious and drinking super sized sodas is not a problem there, it begs the question... Why was this law passed then, if it is completely unnecessary and redundant? Add to that the fact that the law will not apply to drinks sold in grocery stores, diet sodas, drinks that are more than 70-percent fruit juice, or that contain alcohol, and it further begs the question of what level of redundant, ignorant hell such a plan was hatched from. As for the whole concept itself of government attempting to regulate people's personal habits, I'm reminded of what a wise man once said: "A society in which people are only free to make good choices is not a free society."
To create a new department (Division of Beverage Enforcement) think of it like the DEA for example. You need a War on something so you can create government jobs and private corporations can then drink out of the taxpayer trough as well providing services and goods for this new "WAR on obesity"
In practice, this just means that kids will buy 2 12-ounce cans instead of a 20-ounce bottle. So it'll cost them more money and they'll consume more sugar than they did before the law. Fruit juice and smoothies are bad, too, but I guess they had better lobbyists. The fruit sugar is "healthier" than high-fructose corn syrup, but there's an awful lot of sugar in those things and little of the fiber you get when eating whole fruit that counteracts the carbs. A McDonalds' smoothie has more calories per ounce than soda.
