In this case, based on the evidence presented at trial, my opinion is that Zimmerman acted unreasonably and should have been convicted of manslaughter.
I honestly hope you NEVER get placed onto a jury, because you'll be the idiot who ignores the facts and evidence and just goes based on your own opinion, assumptions, guesswork, and hunches. Hopefully if you ever do end up on a jury you'll just hang the jury instead of convicting someone who is not guilty or setting free a guilty person.
