You need to realize this is being used to contradict Zimmerman, not support him.
The funeral director has no right to be spouting like this, it’s against his profession to do such a thing, but be that as it may...
The anti Zimmerman side is saying that Trayvon would’ve shown bruising on himself if he had repeatedly hit Zimmerman, and that no such injuries showed on his corpse.
Therefore they are saying Zimmerman (and the eyewitness) are lying about Trayvon physically attacking him.
On another thread FReepers are pointing out that dead people don’t form bruises. And Trayvon was shot and killed at about the same time he was slamming on Zimmerman.
Specifically, his hands.
I used to repeatedly punch concrete blocks, and never had a bruise. Why would Trayvon have bruises on his?
Or maybe it's that it's harder to see bruises on a BLACK PERSON. I mean.... can you even tell when a black person has a 'tan'?
