Maybe. Or perhaps Martin simply ends up getting shot dead by a cop instead of an armed citizen. Happens all the time.
See, that's fun part of the "What If" game - it's all 100% immaterial.
This has nothing to do with “what if,” except in your mind. Dispatch discouraged Zimmerman from getting out. He ignored dispatch and continued. Too bad for him and Trayvon Martin, wouldn’t you say? He ignored Neighborhood WATCH policy and did more than watch.
Zimmerman bears a heavy responsibility in this, regardless of legalities.
