Miami police

Two former Biscayne Park police officers pleaded guilty Friday to framing an innocent teenager with a string of home burglaries at the direction of the chief so his department could boast a perfect property crime-solving record.

The city of Miami launched a partnership on Wednesday with a neighborhood watch social network in order to help police investigate crimes and share safety alerts. 

'Neighbors' by the doorbell security company, Ring, is a free app that allows residents of a neighborhood to collect and share with each other videos and photos of suspicious activity. Thousands of people in Miami already use Ring's security system, according to the company's representatives, and the city's police hope Neighbors will help them solve crimes faster.
