Expensive and aggressive lawyers - do you work in the courts/law/police? I think you (and everyone else who keeps using the ridiculous narrative) dont understand that this is what solicitors are like, the solicitors for the families will also be 'expensive and aggressive'.
The police and CPS have spent months and months investigating information which they will have sought out in order to bring prosecution, they dont seek out information to conclude no charge, they actively angle their investigations to try to find culpability.
