POV article name 

"Constitutional crisis" doesn't seem neutral to me. Also, it's ambiguous). The focus on the "Constitution" seems to imply one or two things:
 That the "crisis" was about Zelaya pushing ahead with a referendum the Supreme Court opined was unconstitutional.
 That the "crisis" was about the lack of a clear cut constitutional procedure for impeaching a president, therefore implying that the coup was justified.
Either way, it seems to divert attention from the coup, to justification for it. That's inherently POV. It takes sides.
What was notable was the coup.
