"The law is not limited to people who are mentally handicapped and thus unable to consent, or who are photographed against their will by their caretakers (the justification discussed in this story). The operative provisions cover people over 60 and the disabled whether or not they are incompetent. One provision, relating to people's being "deemed incapable of consenting," would cover only "an elder or a person with a disability adjudicated as incompetent by a court of the commonwealth," but I don't see how this would stop liability under the other provisions, since consent is no defense under the other provisions in any event. (Plus if they just wanted to bar exploitation of the incompetent, why not simply say "anyone adjudicated as incompetent by a court of the commonwealth," with no limitation to elders or persons with disabilities?)"
