Broadcast media outlets in Los Angeles have been asked to avoid showing the “tactical movements” of officers during live coverage of the manhunt for Christopher Dorner, the ex-LAPD officer who allegedly shot four police officers Thursday morning.

“The Los Angeles Police Protective League respectfully requests that media outlets broadcasting live images from Big Bear discontinue showing the tactical movements of officers searching for Christopher Jordan Dorner,” a representative of the union wrote in an email to broadcast media outlets Thursday afternoon. “We request the assistance of the media in helping to protect the officers searching for this murder suspect.”

LA stations have been in various degrees of continuing coverage throughout the day. The stations have provided aerial coverage over Big Bear, where police have been focusing their search efforts. The news helicopters have occasionally captured shots LAPD officers in the park (like in the screengrab above, from KTLA‘s coverage).

A representative for the union said the stations have been receptive to the request.
