The first time that witnesses gave their testimony there were simply witnesses to something that happened. They gave their account as they believed that they saw it.
The second time the witnesses gave their testimony they were afraid. They thought better of endangering themselves. The obvious race madness that had taken place since their first testimony has put them in fear of their lives and their families.
I can understand why they would change their stories. They did change their stories. It's too bad because they may end up getting themselves in trouble anyway.
Also, they may very well have guaranteed Zimmermans acquittal.
Just my opinion
