Mr Berger has problems. He is in a state of self denial. Text messaages show he is out of touch with reality. My concern now is for those people who are around him in confined places. He is blaming all of his troubles on "others". I believe that until his situation is resolved, his briefcase and Berger himself should be checked for weapons whenever he enters the room.
This is an accident waiting to happen. How many innocent people will be hurt when it happens?
