The publication, which deals with the right to lie of the perpetrator of a crime, the later suspect, suspect, accused and finally convicted, is undoubtedly controversial because it treats the right to lie of the above-mentioned persons solely as a means of defence, and therefore does not exhaust the features of both the crime of aiding and abetting, as well as other crimes aimed at avoiding criminal liability, hindering the conducted proceedings, simulating illness, or using documents containing false content. It considers whether in explanations, either false self-incrimination or lying incrimination of innocent people constitutes an abuse of the right to defense and is the basis for criminal prosecution, including crimes at private indictment, e.g. defamation. It is based on observation of practice, including the use of illegally obtained content contained in documents, media, computers, or from cyberspace. It points out that the decisive factor for criminal liability is the intention of the perpetrator of the crime to avoid responsibility and suffer punishment, which in a way begins at the moment of its commission and ends on the date of serving the sentence.
