When dealing with criminal cases of the elderly, we should make a comprehensive evaluation according to the nature, circumstances and social harmfulness of the criminal act to ensure the fairness and rationality of the judicial decision. At the same time, in the process of dealing with crimes committed by the elderly, we should respect their rights and interests, take into account the physical and mental health problems that the elderly may face, and take appropriate legal measures and criminal sanctions.
In a specific case, if there is evidence to prove that the 83-year-old landlord's obscene behavior is true, he should be punished and punished by the corresponding laws, and should not be slightly dealt with because of age and other factors. Of course, if the criminal act is minor, it can be given a lighter punishment according to law. But this does not mean that crimes committed by the elderly can be exempted from punishment or dealt with lightly.
I hope my answer can help you.
