It would be nice if someday before our elected officials try passing dumb-ass legislation, they take into consideration all the time and effort the taxpayers are going to pay to implement and then summarily rescind the stupid things - especially on one or more appeals.
Just like the laws requiring you to proffer a drivers license to track and purchase over the counter decongestant containing the base element for meth. It hasn't stopped the number of meth labs, but boy has it bolstered revenues for various IT groups managing that boondoggle via our tax dollars.
If it was really key they ban large sized soft-drinks - just put your money where your mouth is (literally) and just outright ban non-nutritive foods altogether. Of course that won't happen nor would it work, but the road leads to the same conclusion - or wall if you're using Apple maps. (Oh c'mon. That was funny.)
If they really wanted to make a difference on the war against obesity, how about laying the smack-down on High Fructose Corn Syrup (HFCS) in general? Or putting parents on naughty lists who have overweight children? "What? Little Johnny's BMI is in the "obese" range? Then off to FOSTER CARE!!! Oh wait. Dad who is drunk and beats his wife apologizes and the court will give him back the kid anyway having something to do with biological parent vs. best interests of the child... but I digress...
I know, make being overweight _illegal_!! Just like trying to ban guns! Make being fat illegal and owning a gun illegal. Being naked in public is already illegal so let's make it a tri-fecta!! PASS A LAW TO MAKE NAKED GUN CARRYING FAT PEOPLE ILLEGAL! THINK OF THE FAT NAKED CHILDREN! No. Wait. That involves a whole set of other laws...
(Yes. I am being facetious on several of those points. You get to guess which ones, though) :-)
