I'm wondering about the reasoning that justifies characterizing the inconsistencies in GZ's testimony as "lies". Given the overall gist of the narrative, I'd expect GZ's account to have many inconsistences just due to the natural unreliability of testimony from people under stress.
Calling them "lies" seems to be circular to me: We know GZ is lying (not just mistaken) because he really murdered TM. We know he really murdered TM because of all the lies (not mistakes) in his testimony.
Actually, they are seen as lies due to both their blatant falsehood, and their remarkable self-serving nature.as examples:
Zimmerman didn't think to move his car on his own, the police dispatcher asked him to.
He wasn't the aggressive he, Martin showed aggression by...um, coming back and walking around his car before skipping off (this one was just bizarre).
Zimmerman didn't want to leave his car, but the dispatcher required that he give an address.
Zimmerman was not worried that Martin might be nearby, and give this as the reason for not giving out his phone number, instead, he looked and Martin was apparently long gone.
Zimmerman didn't want to be on the move, he even said that the cops could meet him at his truck. You know, the one he didn't know the address to, because he had gone running off.
When the Martin-hulk reappeared from the nonexistent bushes or the shadows or whatever, and immediately tackle-punched Zimmerman, Zimmerman both fell flat on his back, and stumbled forward for several yards.
Zimmerman was so bashed up, having been smothered and having his head bashed into concrete, that he immediately jumped up and tried to restrain Martin, who he thought was still a threat, but was suddenly uninterested in yelling for help about. Also, he had no need whatsoever to go to the hospital, despite having his head bashed against concrete dozens of times.
And also, the Zimmerman's have no money, and Zimmerman himself turned over his only passport. Unless you count that hundred thousand in donations, and that spare passport.
That last one is key. Yu can choose to believe that he just has astonishingly bad memory that just happens to misremember things in a self-serving manner, but I'd consider this to be rather naive. Yes, "liar" is usually a judgement, and I'd say it was wrong if he had made any one mistake that made him look good, along with one that made him look bad. Instead, he seems to be telling falsehoods about nearly everything, and all in a self-serving manner.
