This particular case has a lot more to do with the actions of a psychopath against someone unable to defend him or herself, vs any perception of disability rights that the disabled individual has.
This is about as far and as away from the Robert Latimer case as you can get, as a comparator - judging purely by the news article.
I work in this field, in the front lines.
No matter how physically disabled an individual is, and no matter what functional level that their cognitive abilities appear to be, these people are human. Humans by their very nature are imperfect. Who are any of us to judge, what is imperfect beyond salvage or redemption?
Disabled individuals can feel, and they can perceive what is being said around them, they can understand when they are being belittled and devalued. Even low functioning individuals have complex thought processes going on, and can have the full range of emotional, reasoning, and cognitive skills that so-called 'normal' individuals have - even if they are internally impaired in some manner, or externally disabled through expressive and communicative skills.
Take a look at Stephen Hawkings.. would you be so quick to put him down like a suffering dog, by his appearance alone?
Some of you individuals really should be keeping your comments to yourself, or reserve your judgements for only your own personal situations in the form of a DNR order in case that the worst should happen. Otherwise - let others live as they are, and as they have the full right to, as equal citizens under both the US Constitution, and the Canadian Charter of Rights and Freedoms.
There are alternatives for care of individuals who are unmanageable by family caregivers alone. Whether that be through Personal Support Workers, Community Living organizational involvement and intervention, or becoming a ward of the State, and being placed into care with a foster family or facility able to care for the individuals physical and cognitive needs. Please note - in Ontario, there is no longer an institutional model to care for individuals - there is no warehousing of the disabled. These individuals, by right, are entitled to live in the community, with community and social supports. The rest of Canada, and to a large extent the US, is following this same model of social responsibility for those that are so disadvantaged.
It's called Social Responsibility - it comes with living in a society that isn't a third-world cesspool where life is cheap, and the disadvantaged are prey, or trash. Some of y'all should try to come to an understanding of that. Yes, there are costs involved, that we all bear in our social support system. Suck it up.
