Indeed, sending a police patrol will only catch the kind of crime that happens in socio-economically disadvantaged communities, which in turn contributes to skewing the data to suggest that more crimes there, which leads to more policing, which leads to more crime, and so on.
Meanwhile, wage theft, over twice the size of all other kinds of theft put together, keeps growing year after year.
Police patrols should be entirely reactive, and not proactive. Proactive policing does not work.
Policing is not causing crime. People committing crime is causing crime.
