Members of the School Safety Advisory Commission recently heard from several tech companies on how to make schools more secure, presentations that will ultimately help shape the commission’s recommendations to lawmakers.

Among those presenting was Alex Carney, former U.S. Marine Corps special operations officer and COO of Critical Response Group, a public safety company that develops emergency response tools, oftentimes for school systems.

“The basics of what my partners and I did when we started this company, we took a mapping communication technique that we used every day and every night overseas during counter-terrorism operations, and we took that and we adapted it to domestic infrastructure, starting with schools,” Carney said.
