This is simply a matter of regulating commerce in residential neighborhoods. CM Gilmore gets to the heart of the matter in her defense of the bill by pointing to cheap accessibility and the fact that police spend their time and resources on the top ten offenders of public intoxication. Cutting the problem off at the source in residential neighborhoods is reasonable for the health and safety of those who have to live around the stores, innocent pedestrians, and school children who onload and offload buses nearby.
If the media is serious in their nebulous arguments for greater law enforcement, then let them get out and make some citizens arrests themselves. Of course, there is always the other tried and true option of raising single serve sin taxes so high that consumption in these neighborhoods is driven down with rising costs. That would really get the grocery lobby and absentee slum lords screaming. I prefer another less regressive way (the same argument about after hours clubs applies to single serve commerce): let's get dangerous commercial blight out of residential neighborhoods and into specific zones and, since journalists are rushing to be the champions of the lords of blight and their patrons, let's designate the zoning proximate to any newspaper headquarters.
