HARRISBURG — Police using body cameras should keep them on to record the entire incident under nonbinding guidelines from the Pennsylvania District Attorneys Association.

The model policy announced Wednesday also says the recordings should be treated like evidence when they involve potential criminal cases, logged as evidence and stored.

Prosecutors say that in murder cases, the tapes should be kept until appeals are exhausted “and the offender is no longer under control of a law enforcement agency.”

The prosecutors want police to consult with them before releasing tapes for public viewing.
