who can be defined as a vulnerable person
Vulnerable adult As defined in the psychology, sociology and social work fields, a vulnerable adult is any person who lacks the absolute most basic (as distinct from mid-level or typical level) human life skills. A vulnerable adult is unable, rather than unwilling, to properly learn or properly maintain these skills, and is usually completely without, and unable to obtain, any family, friends, acquaintances or other assistive persons in their lives to offer education or assistance in these areas (see: abandonment). To be classed as vulnerable, the adult's circumstances must be unable to be altered or improved by the adult's own individual actions without direct assistance from a more typical adult. The vulnerable adult must also be shown to be, on some significant level, a risk to him or her self if assistance is not provided.
Intoxication defense In criminal law, the intoxication defense is a defense by which a defendant may claim diminished responsibility on the basis of substance intoxication. Where a crime requires a certain mental state (mens rea) to break the law, those under the influence of an intoxicating substance may be considered to have reduced liability for their actions. With regard to punishment, intoxication may be a mitigating factor that decreases a prison or jail sentence. Numerous factors affect the applicability of the defense.
