>His behavior doesn't add up. <
His behavior already reveals stark inconsistencies that question the mainstream explanation of events. For example, he opened fire on innocent people but then calmly surrendered to police without resistance. This is not consistent with the idea of "killing everyone."
Furthermore, he then admitted to police that his apartment was booby-trapped with explosives. If you were really an evil-minded Joker trying to kill people (including cops), why would you warn them about the booby trap in advance? It doesn't add up.
