In his advisory role, Harrell, a leader in national security, school safety and security, and enterprise security risk management, will help SDS understand the national security implications of gun violence and active shooter threats. 

He will also educate the public about solutions like gunshot detection and integrated security technologies and how they are essential to managing critical incidents and mitigating risk. 

“As the United States continues to struggle with gun violence, part of the solution must be technology solutions that reduce risk and aid in law enforcement response,” said Harrell. “I’m proud to be part of the team.”
