Not every human problem deserves a law.
California Gov. Jerry Brown wrote in 2011 after vetoing a law that would have punished children for skiing without a helmet. Brown often writes explanations for why he vetoes a bill, which is usually because he doesn’t like bills that can be seen as posturing, that could have unforeseen complications or that replicate existing laws. “This is a governor who relishes his role as the adult in the room,” says Thad Kousser, a political scientist at the University of California, San Diego.
