Tragic events lead to new prevention and response strategies. We recognize that there are dangers in our communities and in our schools. These realities call for an enhanced focus on safety. The decades-old school fire drill has evolved to active shooter/threat drills as threats have escalated and materialized, often with tragic outcomes. Our nation is seeking new and innovative ways to keep children and adults safe in school settings. Far from simply developing techniques to respond efficiently to an active incident, public safety officials are also exploring technologies to gauge and prevent potential crises. And they are sharing their ideas and results. Across the country, entire communities are rallying and dedicating themselves to being proactive in preventing school violence. There is much talk about how existing programs can be reinvigorated, what new technologies can be created and how training tools can be distributed to school resource officers (SROs), administrators and local law enforcement agencies. Modern threats are being addressed with modern technology, strategy and resolve. The U.S. Department of Justice's National Institute of Justice (NIJ) is a leader in identifying and sharing new training and technology with law enforcement and other first responders. Since Congress passed the Safe Schools Initiative 15 years ago, NIJ has worked collaboratively with other federal agencies on behalf of our nation's law enforcement to answer the call to develop tools and strategies to boost security in our schools. Front-line professionals are working more closely with teachers and administrators, students, parents and community leaders to create alliances that will transform our nation's schools.
