The police investigate crimes by recording witness statements and collecting evidence. If the evidence points to a person's guilt, they file a charge sheet in court. For a fair trial, procedures must be followed like giving the accused a copy of the charges, holding an open trial in their presence where their lawyer can cross-examine witnesses, and the judge announces the sentence according to law.

2. The Role Of Police:
One important function of the police is to investigate the complaint
about the commission of a crime. An investigation includes recording
statement of witnesses and collecting different kinds of evidence. On
the basis of the investigation, the police are required to form an
opinion. If the evidence points to the guilt of the accused person,
then they file a charge sheet in the court.

be observed. A fair trial ensures that Article21 of the
Constitution is upheld. In a fair trial, the accused person is
given a copy of the charge sheet and all other evidence that
is presented against her. The trial is held in an open court
in a public view. The trial is held in the presence of the
accused. The accused is defended by a lawyer. The lawyer
is given a chance to cross-examine the prosecution
witnesses. After all the procedures, the judge announces
the sentence only in accordance with the law.
