First of all it's not against the law to have mental illness. If the person's behavior is not harming anyone but just appears 'crazy' to you, then you do nothing but avoid that person if you are uncomfortable. Only when a person's behavior is a threat to others or themselves, do you need to call someone. You call 911. The responders should be trained to deal with 'crazy' behavior.
