I am pretty sure it is because it did not have a bill of rights. Hope this helps!
The correct answer is "Elected leaders were capable of abusing their power."
For Lyndon B. Johnson, he abused the powers given to him in the Gulf of Tonkin Resolution passed by the United States Congress. His massive escalation in Vietnam despite the lack of US success shows how he abused his executive power.
For Richard Nixon, he tried to cover up a huge break in to the Democratic National Convention headquarters at the Watergate complex. He tried to use the excuse of "executive privilege" as a means to keep his recorded conversations from the American public.
Human societies from the Paleolithic to the early Neolithic farming tribes lived without states and organized governments. For most of the Lower Paleolithic, human societies were possibly more hierarchical than their Middle and Upper Paleolithic descendants, and probably were not grouped.
