@Lustig Andrei,
This is one of the many examples in which the so-called gospels have got everything wrong. Pilate existed, although many scholars disputed that for a lack of evidence, until Israeli archaeologists unearthed an inscription in about 1960 or -61. But he was not a proconsul as the gospels claim--and in fact, at that time, proconsuls were not appointed as sub-provincial governors. He was a prefect, as the inscription shows. As a prefect, he had no authority to try or execute anyone. He would have been obliged to send any accused to the Legate of Syria, his superior, to be tried and, if convicted, to be executed.
Whether or not this joker existed, there is a great deal of reason to question the accounts of the gospels, because they get it wrong, wrong, wrong again and again. Given that the god-botherers insist on their moral authority based on what they claim are eye-witness accounts of their boy Jeebus, it is very important to confront the errors of their scripture, which are legion.
