Trayvon Martin-George Zimmerman
Stand your ground law was used
Stand Your Ground is the problem
Because killing someone without witnesses should not be an <i>affirmative defense</i> claim of "self defense" that has to be <b>disproven</b> beyond reasonable doubt. Prior to "Stand Your Ground" (SYG) crap laws were put into place, burden of proof was on the defendant to prove his or hers allegations that their affirmative defense claim was valid either by the preponderance of the evidence or clear and convincing evidence.
SYG has flipped what had been standard burden of proof for an affirmative defense on its head.
