Their was an incident locally some years back that at first didnt seem to have any justification for the FBIs involvement. The long and short of it was that because the internet was involved the crime had “crossed state lines” so wasnt solely local jurisdiction any longer.
If the shooter said anything, coordinated anything, bought something for that event, and did it online then by the “crossing state lines” argument they automatically could be involved.
Good points. Does the fact that Kirk crossed state lines for the Utah event have any relevance?
