Just to clarify: that concept is limited in applicable scope to criminal charges. As demonstrated by Zeke's case, while not perfect but simply most recent, actual proof and/or charges are not required for penalties to be assessed to individuals. Even in legal terms, civil standards are far less strict than criminal (remember OJ, innocent of criminal murder and liable in civil wrongful death?)
Anywho, only reason for pointing out is "innocent until proven guilty" will not be the strict standard when investigating and analyzing such situations...a guideline, perhaps, but that's as far as it'll be applied
