You have to reasonably think your life is in danger...which means that a reasonable person would conclude that your life is in danger...you don't get to decide that for yourself based on whatever standard you like.
You seem to be very skeptical about anything and everything that involves chasing Trayvon down and confronting him for no reason whatsoever, even when the 9-1-1 call confirms that it happened exactly that way, and also seem to accept wholeheartedly that Trayvon attacked Zimmerman, was bashing his head into the ground, and that Zimmerman had to shoot him to save his own life, for which conclusion there is very little evidence at all save for Zimmerman's own story.
That brings me back to the very beginning of this argument, which is that folks are willing to make their minds up based on political beliefs rather than anything at all like facts or evidence.
The evidence will be presented to a jury, will be distilled down into relevant facts, and the law will be applied to them...then we will know what happened as well as possible.
Until then saying that Zimmerman was in fear for his life or was having his head bashed in is as reasonable or logical as saying spacemans did it.
Fish on...
