For believing that he is a patsy...no.
Only the person experiencing empathy can express their empathy.
I spent 10 years trying to help a person who was possibly wrongly convicted. Very much like the Brueckner case where his history meant not many had much empathy for him. It wasn't a matter of whether he had done the crime but "he'll do, throw away the key".
Even I had times the thought why am I trying to help this bad person.
But our justice system is supposed to convict the right person for the said crime.
Life imprisonment for a crime you didn't commit? Can you feel some empathy for someone in that predicament?
Bias by the police and the prosecution can lead to stacking the evidence against the suspect/accused.
Where vital evidence that might have helped the accused is not disclosed.
I will say I have some empathy for Brueckner for the fact he is being treated as a guilty person before the trial has been completed.
