premise: Good  cloth hangings of Creole scenes, seashell jewelry, straw mats and hats, particularly from Saint-Barth??lemy, local rum, and conch shells (beautiful specimens can be had for just a few francs apiece from curbside peddlers near the maritime terminal, but only when a cruise ship is about to depart).
hypothesis: A recent police crackdown has resulted in the permanent absence of curbside peddlers near the maritime terminal.
