None of those details have a bearing on who started the fight.
They have some bearing, because they indicate that Zimmerman was losing the fight. It is more likely for someone to be losing the fight if they were attacked by surprise.
More importantly, it shows how this story is being spun and important details that are being covered up by the MSM.
By reading the MSM articles, you would believe that Zimmerman chased down a little black boy, beat on him, and then shot him.
These details show that narrative to be very unlikely.
No but it certainly shows that the media is willfully lying out of their ass.
Out of curiosity do you not want both sides of the story?
