I think it was stupid what George Zimmerman did, I certainly wouldn't walk into that kind of situation with a gun. These idiots (Zimmerman) need to realize that the law in most cases is like the minimum standard. Just because you can do something doesn't mean you should.
Although it was stupid, it sure as hell didn't warrant a violent attack that threatened George Zimmerman's life...
Anyone that doubts Trayvon could out run Zimmerman is delusional.
Following someone isn't a crime, asking questions isn't a crime. Looking out for your neighborhood (especially after a string of burglaries is admirable).
