What happened - and it did happen - is precisely what police don’t want. They want to form a theory from individual witness accounts. In this case, they received a group theory that may or may not have been influenced by dominant members of the group. Given the risk of prosecution by having left their children unattended, it’s easy to understand the motivation.
We are not going to agree on this and I’m okay with that. But, IMO, collusion between the group is so obvious, I’m troubled that I have to state it.
