Rio de Janeiro police officials say the city plans to use a facial-recognition system at its famous carnival.Rogerio Figueiredo, the new head of the state police, said in an interview published Monday by the O Globo newspaper that cameras will scan both faces and car license plates, reported Voice of America.”If (the cameras) identify an individual under an arrest warrant, or if a stolen vehicle drives through the area, an alert will be sent to the closest police car,” Figueiredo explained. “It's a fantastic tool. It's time that the police modernize.”After new anti-crime president Jair Bolsonaro was installed January 1 and ally Wilson Witzel taking over as Rio's governor, local authorities are poised to take a hard line on crime.Witzel, for instance, has evoked using police snipers to kill armed suspects, even if they are not directly threatening anyone with their weapon.Reports say the governor is also looking to acquire Israeli surveillance drones that are capable of firing on suspected drug gang members.
