I'm slightly glad about this. For a long time, undesirables (junkies, blacks etc) would have gotten more police harassment if they were running businesses from the street whereas a blind eye was turned to nice middle class kids doing what is almost the same thing.
Now the cops have to apply the law to everyone, and yes, if you want to give the police the power to move that person who makes you uncomfortable then you must give them the responsibility to shut down the lemonade stand.
