The San Antonio Police Department (click here) will expand its officers’ use of body-worn cameras under a measure approved by City Council on Thursday.
As part of a midyear budget adjustment worth $1.3 million, council allocated $320,000 for 251 body cameras for bike patrol and park police officers..
Earlier this year, city officials said they hoped to acquire the cameras no later than 2016, but emphasized that the cost of data storage was a looming concern. The department has been using body cameras on a trial basis.
