Why rig the apartment, crank up the music, shoot into the crowds, AND THEN WARN THE COPS THAT THE APARTMENT IS RIGGED? Why did Holmes tell them about the booby traps? Does he have split personalities? jekyll vs hyde? james vs joker? Is James possessed? Did his demon help him get such good grades? Where'd James get the $$$ to buy the ammo, guns, body armor, smoke bombs, booby traps, etc? Maybe he bragged about the bombs to the cops cuz James assumed that someone had already tripped a trap and been blown up while tryna turn off his loud ass music. Tough to plead insanity when you're smart enough to do all this without an accomplice or co-conspirator.
