In a perfect world the person that had Zimmerman on the phone would've told him to stay on the phone

... then the whole incident would have been recorded.

We could have heard what Zimmerman said to Trayvon and could have heard more clearly Trayvon screaming for help.

Or IF Zimmerman knew his whole phone call was being recorded he would have done everything differently, and Trayvon would still be alive.

1. In the world before cell phones

We'd have essentially zero evidence of what was said by anybody. I suppose we're getting to a place where each and every action taken by a person outside their home (and significant parts of life within it) are going to be recorded.

Not my idea of a "perfect" world...
