Lynwood, a suburb of Chicago, has a new municipal ordinance: You can be fined $25 if three inches or more of your underwear is showing in public. The ordinance is aimed at droopy-drawered young men in particular. The rationale is that economic development in Lynwood is adversely affected by these fashion violations because they keep shoppers and retailers away.
Predictably, this has caused a storm of protest, with various groups charging that the ordinance is (pick one):
* sexist because it's aimed at males.
* racist because it targets the fashions of young men of color (This is the ACLU position).
* impossible to enforce without wandering around with a ruler, measuring BVDs, and cops should have better things to do with their time.
* an infringement on the personal right to wear whatever one likes.
When I was teaching Odyssey last week, we did world-building. One of the things we considered was: What is a crime in your SF or fantasy society? This question is good for yielding plot developments. However, no one, including me, came up with "exposed underwear."
You just can't predict even the near future.
