I have considered Martin's history the entire time (it's up in one of my previous posts) - it's why I continue to say they both are at fault (unlike those who keep defending Zimmerman as if he's a saint).
Martin's history is school-yard fights, marijuana use, and school suspension. Zimmerman's is assaulting a police officer, resisting arrest, (potential drug-use?) and domestic violence resulting in a restraining order.
How many 17 year olds are suspended from school for fighting? How many have tried marijuana?
How many 28 year olds get to continue carrying a gun after police assault / resisting arrest / domestic / drug charges?
You forgot
,How many charges are lessened after facts are collected, not just here across the board?
