Yes imo.
We know that her interviews with DS Jones did not follow protocol. Eg she was placed in the police training college without access to a solicitor and 'advised' not to speak with anyone on the outside. She was apparently supervised at all times.
DS Jones was a middle aged experienced police officer with decades under his belt. JM was a just turned 21 year old female.
I believe he made all sorts of threats about JM going down as an accessory on the basis JB called her before the police insinuating JM was aware of JB's plans. Putting to her SC could not have shot herself twice. Plus she was involved in OCP burglary and the selling of cannabis with JB. And the cheque fraud with SB.
