exhibit #1 and one of zimmermans 1st group of lies that he did not know the DA had evidence for.
1.) zimmerman " I scream for help"
2.) there was no words exchanged or preallocation
3.)zimmerman did not know that the 911 calls made would capture the screams for help and 2 experts from the news would analyze the contents and conclude it it not zimmerman screaming for help. so the only other reasonable explanation is it is TRAVON MARTIN screaming for help and zimmerman lied and reversed the story of who was calling for help to fend off an aggressor
