Input: The armed forces officially took over Rio's police on Friday under a decree signed by President Michel Temer.
 Temer 's extraordinary decree came after Rio's governor asked for federal help following an exceptionally violent Carnival. During the holiday  there were several muggings  armed robberies and violent confrontations.
 Temer  met Monday with ministers and lawmakers to discuss the intervention.
Hours before Congress was to take up the measure  an opposition party asked the Supreme Court to suspend the vote  saying  Temer  had not followed the rules for issuing such a decree and saying the move had "political and electoral motivations." No ruling had come from the top court by the time the session began.
 Temer  and  his  ministers have gone to great lengths to emphasize that the president is ultimately in charge of the operation  providing civilian oversight of the military. That reflects deep unease in a society where many still remember the 1964-1985 military regime.

Rio could be 'laboratory' for solving Brazil's crime crisis
