Exactly. They wouldnt which means this group knew in advance, they arent abductees. They left behind things like keys, wallets, phones, wrist watches, etc. You dont do that without a purpose. Some with bags, the general remembered to take his pistol but nearly nothing else. They are runaways, whether they went into a program to hide them or something like that we may never know. Did they all leave home to go into hiding because they were warned there was plot to kill them? Did they have to leave knowing that there was a plan to abduct them and disrupt their research. We cant know yet but at least 4 got away, whether from “the Chinese” or “little greys” is irrelevant.
