A more thorough explanation:

PIR

PIR stands for Presentence-Investigation Report. It is a report that is prepared by a probation officer to help a judge determine an appropriate sentence for a defendant who has been found guilty of a crime. The report includes information about the defendant's background, criminal history, and other factors that may be relevant to the sentencing decision.

For example, if someone is convicted of a drug offense, the probation officer may investigate the defendant's history of drug use, employment status, and family background to help the judge decide whether to impose a prison sentence or probation.

Another example would be if someone is convicted of a violent crime, the probation officer may investigate the defendant's history of violence, mental health, and substance abuse to help the judge determine an appropriate sentence that takes into account public safety and the defendant's potential for rehabilitation.

The examples illustrate how a PIR is used to provide the judge with important information about the defendant's background and circumstances that may be relevant to the sentencing decision. The report helps the judge make an informed decision about the appropriate sentence that takes into account the defendant's individual circumstances and the need to protect public safety.
