Isn't Harvey supposed to be like 6'2"? 182 is a little light for that height isn't it?
also Harvey scratched up the coin himself, hard to have a violently scarred coin from corrosion, and his psychotic break came more from the corruption in the police force he was working with than just getting his face fucked up.
its funny in the tommy lee batman movie, batman is(for whatever reason) in the court room during the trial, and tries to save that Harvey from the acid....with a thin ass file folder
