Greenfield, Mass Police Department: FYI: The Greenfield Police in conjunction with the Mass State Police and the Greenfield Public High School conducted a "lockdown/shelter in place" drill at the high school The purpose of drill is to ready the kids in the school in event of an emergency other than a fire. During the drill members of the MSP K9 team conducted a training on canine locker searches. We are trying to ensure that the school remains a drug free environment. You may hear the students talk about the Police and K9's presence in the school. Unfortunately, we are not at liberty to discuss the results of the locker searches.
