if this was a terrorist attack:
why was there a warning?
BLM, Antifa, islam, china. They do not care about people. What if this is a "qanon" attack.
patriots usually would be with their families but patriots would also be the only ones who might be concerned about "real" people.
Of course this is a FF at this point. We have owls in the area as well. We also have the china date of 11/11 and a satanic sacrifice day. FBI and ATF were on scene almost instantly. THe warning thing though is the fishiest part of this.
