概要	Journey-to-crime analysis studies how far and where offenders travel from an anchor point — usually home — to commit crimes, and inverts that pattern to infer an unknown offender's likely base. The aggregate distance-decay regularity (most crimes occur near the offender's home, with frequency falling off with distance) underlies geographic profiling, formalized by D. Kim Rossmo in 2000 to prioritize the search for serial offenders.	Routine activity theory explains predatory crime not by the supply of motivated offenders but by the everyday structure of legal activities that brings offenders, targets, and the absence of guardians together in space and time. Proposed by Lawrence Cohen and Marcus Felson in 1979, it argues that crime rates can rise even when offender motivation is constant, because changes in how people work, shop, and spend leisure time alter the opportunities for crime.
