Algorithms are not unbiased processing calculations. In addition, systematic bias also contains police officers bias. Greater tendency to imprison one sort of group or in one certain location highlights those areas to the algorithms. A term that must be defined is crime displacement. According to Guerette, “Crime displacement is the relocation of crime from one place, time, target, offense, or tactic to another as a result of some crime prevention initiative.” There are five different forms of displacement. There is temporal, where offenders change the time at which they commit crime. Spatial, displacement were offenders switch from targets in one location to targets in another location. Target displacement is when offenders change from one type of target to another. Tactical displacement is when offenders alter the methods they use to carry out crime.
