The whole, "Martin is dead so Zimm must be lying" argument is pretty great
Let's say everything that Zimmerman said is true. It still does not qualify as self defense to me.

Just look at the facts.
Zimmerman assaults Martin (see Trim's post).
Martin retaliates with a punch to the nose.
Martin gets on top of Zimmerman, maybe punches him once, and covers his mouth to keep him from screaming for help.
The cops are already on their way and should be arriving any minute.
Zimmerman has a gun and can use it if he continues to get punched. He does not look like he was punched more than once or twice.
Multiple eyewitnesses are present to potentially break up the fight and have told Zimmerman that they are calling 911.
Zimmerman shoots Martin in the chest. Has very minor wounds consisting of a bloody nose (no break) and 4 or 5 tiny scratches on the back of his head.
