Buffalo Police: Officers have been threatened since Dallas shootings

The Buffalo Police Department is making immediate changes to keep its officers safe following the ambush shootings in Dallas that killed five officers and injured seven others. 

Until further notice, Buffalo Police Commissioner Dan Derenda says all officers will be riding in patrol cars with a partner and not alone, as has been protocol.

While off-duty, Derenda has also urged officers to carry a firearm and refrain from wearing any clothing that identifies them as a member of law enforcement.

Derenda says his officers have received threats, including that they would be shot, since the shooting rampage in Dallas Thursday night.
