There is plenty of evidence. You are just making the absurd insinuation that it needs to reach a standard of beyond a reasonable doubt. The only problem is for your stance is that it's the prosecution that has to reach that standard against Zimmerman.
If you have real evidence then post it. But you won't because there is none.
I have posted it. If you'd pull your head out of your arse, you could see that.
You say that you have real evidence that Martin attacked Zimmerman --- I say that you are not being truthful.
