Police officers from Ossining, Briarcliff, Croton take part in emergency drills
A number of local police departments teamed up Friday to prepare for the worst.
Officers from Ossining, Briarcliff, and Croton took part in emergency drills at Anne M. Dorner Middle School in Ossining.
The drills come after last week's deadly shooting at a San Bernardino elementary school.
All three departments will continue training on Monday.
