i don't know how much it applies, or even how true it is. i'm not a 911 operator, nor do i know anyone who is...
that said, i have heard that it is standard procedure to direct the caller to avoid ANY kind of confrontation if at all possible, no matter the circumstances, to avoid any liability.
i don't think the operator was wrong in tell him to not pursue, or engage young martin. zimmerman had a responsibility to his community (or felt he did) to investigate the situation. what happened after that is unclear.
racism is alive and well in the US, but it's not what some people make it out to be. from what i've seen, there is a lot more black on white racism than the opposite. got several racist black families that live on my street.
there are enough problems in this country, the media should not be trying to start a race war. in my opinion, that is all that they are doing (not that they can really do anything else effectively).
i dunno, that's the best my overworked, sleep deprived brain could come up with for a response. hopefully it made sense. doubtful, but i can hope.
