Apparently Zimmerman was his own law - nobody was going to tell him what to do - This poor kid was killed by THE JUDGE!
If you read through the record of his 911 calls, it appears that Zimmerman was a busybody, almost the stereotype, who in old movies is played by an old woman.
LOL, are you sure you haven't been watching too many Westerns lately? Seriously....no need to get so emotional. The facts are still coming out. Let them come. Right now YOU are doing the judging.
