That's what it's looking like, yes; although we don't really know as of yet exactly what the FBI raiding party encountered when they executed their -- apparently -- open-ended 'no holds barred' warrant.
Anyway, if it was a message, then certain groups of people heard it, loud and clear. But it won't have the result that the leftist controlled and politically corrupt FBI expected; those people NOT being sheeple beta-male leftist types.
