Hypothetically, a person who believed that breaking the law was impossible, ought to also be for the abolition of police, prisons, and the criminal justice system in general, since without crime, those things would lose their justification (at least to the general public) and therefore be a major waste that locks up only people who would have to be innocent. However, it’s somehow hard to imagine the sort of person that would suggest illegal things don’t occur, actually taking such a position.
