I fail to see why any of the things you stated indicated a domestic shooter are not equally applicable to a foreign shooter.
Stay well - Stay safe - Stay armed - Yorktown
In some cases they could be applicable to a foreign shooter, such as the ransom. The reason the items are on the domestic list by themselves is that I feel the reasons (keeping the note from the public, for example) are more likely explicable by a domestic nut. You are quite correct, though, in that there could be logical reasons a foreign terrorist would use those behaviors.
I am trying to keep an open mind about this, because it is too easy to start to sift evidence based on one's pet theory. It isn't very easy to do, however.
Boy, this is pretty draining after a month. It's driving me to consider "binge" shopping. That's always relaxing. Maybe "lobster" this weekend, too.
Stay safe! Give someone a hug today!!
