If you want to read the arguments deployed by those who are either philosophically or temperamentally opposed to telecare, a good place to start is the Smart House Meets The Nanny Camera article by Janet Colliton, who is an elder law attorney. [Please note this link seems to be a bit unreliable – try later if it does not work first time.]
For a balanced and in-depth view on the pros and cons of the issues, you can’t do better than read Guy Dewsbury’s SMART Thinking telecare FAQ webpage, particularly the ‘issues’ section that starts about halfway down as mentioned in Tuesday’s TelecareAware posting.
