DI Denton's arrest
Perhaps I'm missing something, but I don't see the grounds for Denton's arrest.
These are the facts as I see them:
1. Denton is a last minute replacement on the night of the ambush and assigned by her superior officer. Apparently she wasn't even supposed to be there.
2. Denton claimed DS Akers suggested the route change to the station. We know for whatever reason it was Denton's idea, but the authorities have no proof that it was.
3. Denton has no previous ties to any of the victims, including DS Akers and the witness under protection, or the killer in the hospital.
4. There was the phone call she made to the nurse's station before the hospital murders, but nothing connecting her to it before she was arrested.
The questions surrounding the route change and the decision to proceed unarmed and without backup prior to the ambush could seeming be a disciplinary issue, but certainly not grounds for a murder charge, much less be remanded without bail.
I know the judicial system is a little different across the pond, but these charges are clearly based purely upon speculation and not even close to circumstantial evidence.
Am I missing something?
