Shine, in a place like the Southside of Chicago or even our Moncrief, your "reasonable" approach would get you mugged 9 out of 10 times. If a creepy guy you don't know is following you in the dark & rain, he's typically up to no good. Regardless of that, no one but Zimmerman truly knows what happened. There were no eye witnesses that saw how the actual altercation started or what was truly said. All we really know is that at some point in the fight, the kid got the upper hand and was killed as a result.
