Fifty years after the introduction of the Crime as Opportunity theory, this paper applies its core insights to a micro-temporal empirical setting to examine how short-lived fluctuations in urban mobility shape street crime. While transit nodes are recognized as crime generators, previous research has remained largely descriptive and constrained by coarse temporal resolutions that overlook short-term opportunity fluctuations. We address this gap by assessing whether brief periods of crowding at bus stops causally increase police reports of non-violent property street crimes-offenses highly dependent on opportunity structures. Leveraging high-resolution spatial data from Montevideo, Uruguay, we implement an imputation difference-indifferences estimator to isolate intra-day variation in passenger flows and test opportunity theory at a micro-temporal scale. Our findings reveal offense-specific selectivity: short-term crowding peaks significantly elevate theft risk, whereas no significant effects are detected for robberies. These results indicate that non-violent property crimes are more sensitive to the presence of opportunity, showing that routine and transient mobility fluctuations exert immediate effects on street crime by reshaping the distribution of opportunities in urban environments.
