It can't and won't appear at trial either. There is no independent reliable, credible and trustworthy on-scene eyewitness, no video. The issue cannot be resolved to the standard of proof that wtc911 demands.
No matter, that's not how the law works, nor is it how people resolve uncertainty in serious issues. There is other evidence, plenty of it.

The standard of proof I "demand" is called just that - proof.
You have just acknowledged that you don't have it.
I could take the exact set of knowns (zimmerman followed martin - martin ran) and say that the fact is that zimmerman confronted martin, showed or reached for his gun and martin started fighting for his life by knocking zimmerman down before he could pull the gun and continued to beat the armed stranger to save his own life.
That version is based on known facts --- therefore it must be true.
Exactly so on that last. Hence my previous comments. BTDT.
