Iran’s criminal policy towards money laundering in the country’s banking system
basic principles governing the course of criminal proceedings, according 
to which every innocent person is presumed, and if he is charged with 
presumption  of  innocence,  the  prosecutor’s  oce  must  prove  his  guilt. 
Despite the place that this principle has in criminal matters and governs 
other principles and rules of criminal law, however, in certain cases of 
application of this principle of transgression, and despite the fact that 
the principle is innocence, and the prosecuting authority must prove the 
material and spiritual elements of the crime, and the accused is not obliged 
to prove his innocence, the task of presenting the reason is shifted and falls 
on the accused. 
The basis for deviating from the principle of innocence is, in many 
cases,  the  very  basis  that  justies  the  rule  of  the  principle  of  innocence 
in criminal matters.in other words , Just as legal justice requires that the 
accused be acquitted in the absence of evidence, innocence and innocence, 
In special cases, where the existence of evidence strengthens the suspicion 
of committing a crime by the accused, the requirement of legal justice and 
public interests is the precedence of the principle of guilt over the principle 
of innocence (Eslamian, et al., 2020).
b. Using informants and special research techniques
One of the methods proposed in the Palermo Convention to detect and 
prove organized crime, including money laundering, is the use of informants. 
Money-laundering research is based on the development of information, 
including intelligence (Standing, 2010). Educating and training informants 
is very important in pursuing money laundering. Informants may be 
airport employees who become aware of the unusual transfer of money 
in and out of the country. Alternatively, are secret members of the police 
who gather news in the course of their mission; for example, undercover 
agents in search of money-laundering services or money launderers who 
want to exchange illicit money for criminals are replaced as criminals? 
Alternatively, he may be a criminal himself who has repented and is trying 
to give his information to the legal authorities. 
Given  the  diculties  in  inltrating  criminal  gangs  and  detecting  and 
arresting them, these remorseful criminals’ information is very important. 
Of course, these informants can sometimes report false information as 
well, in order to mislead the police in nding the trust in the reports. In 
any case, these criminals have expectations for any cooperation with law 
enforcement ocers. For this reason, Article 26 of the Palermo Convention, 
entitled “Measures to increase cooperation with law enforcement agencies” 
was adopted. It also urges member states to take action , to encourage 
individuals and members of organized crime groups to provide useful 
information about the details, The nature, composition, structure, location, 
activities of these groups and their relationships with other groups, crimes 
committed or may be committed by these groups as well as to provide
