With regard to utility in deterrence, which you mentioned about minimum sentencing, a minimum sentence keeps the perpetrator — the one now found guilty in a court of law — from harassing the victim during at least a certain period of time and allows some possibility of the victim being able to readjust without that additional impact.
Concernant l'utilité de l'effet dissuasif, dont vous avez parlé, les peines minimales obligatoires empêchent au moins les criminels de harceler les victimes durant un certain temps et elles permettent, dans une certaine mesure, aux victimes de se réadapter sans subir d'autres conséquences.
