How many of the victims were Jewish? Did he say anything while he was shooting? Had he been there before—did he have a beef with anyone there?
Sure the FBI knew of him. But our laws don’t allow the government to pick up everyone e they “know of.” And we don’t want that happening.
I am not sure what FR folks want the FBI to do? If he hadn’t committed any crimes before pulling the trigger, there isn’t much they can do.
I saw a thread that said he was laughing during the shootings.
