Answer:
The judge ruled that Violet's confession is inadmissible, because her confession was forced and involuntary.
Step-by-step explanation:
A confession is a formal statement a person makes voluntarily, admitting he or she is guilty of committing a crime.
The 14th amendment of the US Constitution states that the police must only obtain voluntary confessions and must not force, intimidate or coerce a suspect to confess to a crime.
In such a case where a suspect is forced to confess, then such confession will be inadmissible in court.
Therefore the judge ruled Violent Violet's confession as inadmissible, because she was forced by the police to confess, and as such, her confession was involuntary.
