##### A model for the movement of petty criminals in and out of prisons assumes that all new criminals arise from contacts of existing criminals with law abiding citizens. Assume there is a mean time $sigma^{-1}$ before a criminal is caught and sent to prison. The mean time for a prison sentence is $mu^{-1}$. Upon release from prison, a small fraction $f$ of ex-prisoners become law abiding citizens with the remainder returning to being criminals. Formulate a model to describe the movement of criminals
