he's using the testimonies of the 9 witnesses (of whom 7 have recanted their statements and said they were pressured by police into declaring him guilty) as a defense for him being guilty
recanted or changed
recanted means the opinion is completely disposed of
changed means modified
the defendant used this wording specifically so people like you would think that the witnesses completely disputed their statements, which didn't happen.
a dude who got executed for a crime of which there is no physical evidence of him committing said crime and of the original 9 witnesses that got him convicted 7 have taken back their statements
>dead security guard
>2 people troy confesses to
nope no evidence lol!
