...but it isn't a plthole. It's stretching the bounds of belief, but it isn't a plothole.
There's many potholes within The Joker's plan.
Take for instance the whole 'bomb in the belly'. Now, first of all, it's a bit of a stretch to know that Joker already put a bomb in someones stomach, because they knew they would get caught. Sure, I'll give 'ol psychic Joker that one. But the very act, of him knowing that it would be his 'ticket out' is beyond ridiculous. He needs to blow it up, by using his 'phone call'. Guess what, you aren't entitled to a phone call by law, that is all made up. But again, I'll stretch that one as well, and give it to 'ol psychic Joker.
BUT, the very fact that he was using that, to kill everybody aorund him, and get Lau out of jail ALIVE(so he can get the money), is a bit much. So you're telling me, that Joker knew the the blast would kill EVERYBODY in the jail, besides him and Lau? And how did The Joker blow up cops that were standing
IN FRONT of him, when the blast came from
BEHIND? If the blast killed the cops, don't you think it would have taken The Joker out as well?
And again, if you go back to the actual definition of a plothole, it says:
plothole definition said:
...These include such things as unlikely behavior or actions of characters, illogical or impossible events, events happening for no apparent reason, or statements/events that contradict earlier events in the storyline.
Trust me, The Jokers plan falls into a lot of these.
