Appeals court rejects Cincinnati's appeal of drug zone ruling
Ends don't justify the mean is the old saying. Labeling a sub-region of the city has the purpose of rooting out crime, but in the process it forever furthers to solidify Over-the-Rhine as the "drug zone" for the city.
Above and beyond that issue is the issue of due process. Additional punishment for crimes not directly administered by a court is what I call a legal problem.
