Yes, it adds up. He had expected to have a prearranged explosion at his apartment draw the police off, and then the booby traps draw more police and first responders off, which would facilitate his escape. Although the explosion occurred, and his neighbors noted the noise, they did not report it to 911, so the police responded more efficiently to the theater shooting reports and captured him. Once he was captured there was no longer any need to kill the police and first responders with the booby traps, because now that he was caught cooperation might mitigate his punishment.

He killed 12 people. There won’t be any mitigation.

But if he thinks he is the Joker is that what the Joker would have done sparing the police of getting blown to smithereens. Seems to me the answer would be No

No longer any need to kill policemen and firemen after all those he did kill.....naw, it still doesn’t make sense.
