LINCOLN, Neb. (AP) — Lincoln police have resumed operation of two security cameras that are focused on the downtown bar scene.

Police Chief Jim Peschong (peh-SHAHNG’) says the cameras will record for three days, then loop over and resume recording, erasing the previous footage. Peschong said investigators won’t watch the recordings unless an officer or victim thinks they captured evidence of a crime.

Police had the cameras installed in November 2012 but shut them off a month later after concerns were raised about people’s privacy. Peschong says police and city officials have spent the past year listening to concerns and balancing public safety against the privacy concerns.
