Once Zimmerman left his truck and decided to pursue, he became the aggressor. And Zimmerman has admitted he was in pursuit. Any other questions?
Once Zimmerman lost sight of Martin there was no pursuit. Any questions?

Prove it. Prove Zimmerman initiated the fisticuffs.
You can spin all the theories you want. But if you can't prove Zimmerman attacked, there is no crime.
In fact, given what we now know about Martin, Zimmerman's story is totally plausible. Martin was justifiably pissed at having attracted attention for walking while black in a hoodie on a dark and rainy evening with his hands in his pockets. So far, so good. But, alas, Martin caused his own death when he unwisely and unjustifiably lost it and attacked Zimmerman.
There's a good reconstruction of what probably happened here.
