The Crazies/Headscratchers


 * When David walks into the morgue, he finds a man with his eyes and mouth sewn shut. when he opens the man's mouth, he mutters "behind....you...". The man that imprisoned him is behind David. How did the man see the Crazy? His Eyes were sewn shut!
 * Actually, if you look closely (best seen when David's cutting the guy's mouth free) you can see that his right eye is still open, sewn over, but open.
 * The man knows that the crazy doctor is lurking around somewhere and would try to attack David. If David hadn't seen him already, then he's probably behind him.
 * The Government tries to cover-up the Nuke as a chemical plant explosion. How on Earth would anybody believe that a chemical plant, which nobody remembers ever being there, had enough volatile chemicals laying around to create a nuclear-sized explosion by complete accident. And how will they explain away the radioactive fallout in the area, unless they're planning to keep the area restricted for the next 10,000 years?
 * That wouldn't matter, either. Every major country in the world would be able to analyze the radiation in the matter of months, and determine that it's origin was a nuclear weapon somewhere in the North-American continent. It wouldn't take a genious to count 2+2.
 * David and Judy are still a good distance away from Cedar Creek when the satellite sees them. Why do they immediately resort to quarantining the city on the mere suspicion that the two of them are infected, rather than sending a helicopter around and gunning them down before they reach the city?
