I read that Michael claims they were watching TV or a movie dealing with such issues, and Terri said something like "I wouldn't want to live like that!" (As most of us probably have!). I've read nothing to indicate that even he claims they had a detailed discussion about precisely what conditions would provide the trigger.
Michael, his brother, his brother's wife claim that.
The judge ruled them credible.
TWO of Terri's friends, who were also there, state the exact opposite. The Judge Ruled them NOT CREDIBLE because they didn't say what the JUDGE wanted on the record.
