You are correct.
But really... once 911 tells you that cops are coming and “you don’t need to do that”... shouldn’t you stop?
He told the operator “they always get away” and that Martin was eluding/running once he (Martin) noticed that Zimmerman was on the phone. I don’t know what I personally would do, but a statement like the operator gave is not an order that has to be followed - even if they directly told him not to.
Sometimes the police appreciate the help, other times they ask that you not follow or make chase because it can be a danger. Tough call, but it sounds like crime in the neighborhood was up and that increase in crime was driven mainly by one demographic if I’ve read the stories correctly.
Just because the amount of calls Zimmerman made were (seemingly) disproportionately about blacks doesn’t mean his intentions were racist. That fact may just point to the truth about who was committing crimes in the neighborhood - no matter how uncomfortable that truth might be for some to accept.
It's my understanding he did....what took place after and before the police arrived is what's in question. And I have no reason to not believe Zimmermans story as we know it currently, and that by the evidence that's been revealed.
