I'm a bit surprised you've already filled 13 pages with this discussion.
When Akai falls inside his car after being shot in the head, you can see the hole the bullet made. you can't fake that, especially if you've got both your hands inside your pockets.
Okay, he could fake the lung shot by having some glass of red substance, and the blood from the mouth could be that he bite his tongue.
This fake blood reasoning, I got the idea from
Also, in the manga the bomb timer was 3 seconds, while in Ep. 504 is 30 seconds. Okay. One may be able to rise quickly, try not to hit yourself with the car's roof and jump out of the car, but I wonder something...
The boy at the aparment where Okiya lived seems to know him from some time ago... (Could just a month, but I'd preberably say two) and I wonder how Akai switched places so easily.
When I say "switch place" I mean that while he was working in the FBI during the whole "Clash of Red and Black" story arc, the boy must have seen Okiya leaving, or maybe he made an excuse and said he'd go on holiday (Rukumichi or the BO spy supposedely entered the hospital just at the begining of winter holiday).
But I don't remeber Akai showing any detective reasoning. I've browsed troguh all the chapters in the manga where he appears and always looks live an impulsive (In the 4 Porsches case, when he saw Conan on TV he made an U turn in the middle of the street) Same happened when he heard Conan in the "Panda" case and hurried to catch James Black's hijackers.
Well, anyway, Gosho - san has left us with some small clues, like Takagi says when questioned by Jodie ("There's something strange about that burnt body, tough)
Well, it's your opinions who could bring down my argumentation, but I only exposed it to try to close all those repetitions about all polotholes suggested in this topic.

EDIT By Jd-: Had to spoiler-out the Christie line. That's one of the best Poirot mysteries; can't let it be spoiled.
