Legal analysis
A mental patient who can't identify his own behavior is a person without civil capacity. The civil act of a person without civil capacity is invalid, and the most important thing is to have a medical appraisal. You can ask the court to prove the patient's condition. If a person is incapable of criminal responsibility, he may not bear legal responsibility, but his family members have the obligation to compensate the victims for related losses and bear the obligation of discipline and protection. For crimes committed by the elderly, we should fully consider their motives, purposes, plots, consequences and repentance, and combine their personal danger and the possibility of recidivism, and give them a lighter punishment as appropriate. Old people also need to bear criminal responsibility for committing crimes, even for special groups, which is inevitable, but what kind of punishment they need to bear depends on the specific case. Older people who have reached the age of 75 and intentionally commit crimes may be given a lighter or mitigated punishment. Those who commit negligence will be given a lighter punishment. The death penalty is not applicable to the elderly who have reached the age of 75 at the time of trial, except those who have caused death by particularly cruel means; Sentenced to fixed-term imprisonment of not more than three years, and those who meet the conditions will be suspended.
