If you are going to go on about rule of law, you have to also acknowledge that Martin had his own right of self-defense. If some random stranger followed you in his car, then followed you on foot, never identified himself to you and then started in on interrogating you for no apparent reason, what does that look like to you, the person being followed? The fact that you cannot acknowledge that Martin had his own right to self-defense is mind-boggling. There is no definitive proof that one or the other started the fight they had, but yet you keep insisting on believing the known liar's (Zimmerman's) story, why? The only thing I'm asking for is that Martin has his own right to self-defense, but you keep speaking as though Martin brought everything down on himself. For what purpose would Martin have to put himself in that situation when, for all he can tell, some "creepy-ass cracker" is following him around and making him fearful of his own safety? Neither man knows the other from Adam but only one is allowed to be fearful of his life.
Someone following you does NOT give you a self-defense claim. If someone is following you you can NOT hit them, or otherwise make violent physical contact with them. If you do so you will be arrested for assault.
The laws in your state, if you do not live in Florida, will be similar. You should understand them.
The physical evidence does not contradict, in any way, the narrative of Martin attacking Zimmerman. In fact, it corroborates it.
Even if you extend the benefit of the doubt to the extreme range of granting the possibility that Zimmerman attacked Martin, even with him causing absolutely no damage to him, it still would not completely eliminate Zimmerman claiming self-defense in shooting him after 45 seconds of unresisting (the only damage he manged to cause was violently bashing Martins fist with his face) punishment from Martin. A very credible argument could be made that Martin's self-defense passed into excessive force and became its own assault.
At this point you have just muddied the water to where a reasonable doubt acquittal for Zimmerman becomes a must.
