My thoughts on the Guilty Zimmerman

Help! What's the proper procedure when you're followed by a random armed nutbag returning home from getting candy & iced tea?

 l guess if l walk thru an alley in Florida and a guy comes at me with a gun and l fight him off - he can shoot me and claim self-defense!

Wait.....what??? Isn`t this what got us here in the 1st place??  To bad his brother didn`t follow this advice.
