Washington • Repeal of Prohibition in 1933 instantly reduced crime by reducing the number of criminalized activities, including some that millions of Americans considered victimless activities and none of the government’s business. Now, America is going to become more law-abiding, the Supreme Court having said that the federal government cannot prohibit states from legalizing what Americans have been doing anyway with at least 150 billion of their dollars annually. This large figure (almost five times the combined revenues of MLB, the NFL, NBA and NHL; 14 times the movie industry’s domestic ticket sales) is a guess and might be much less than the actual sum that Americans wager on sports.
