In the 12 years following 9/11, multiple agencies have worked to create radio communications inter-operability. The goal was to let first responders better communicate with one another. That effort appears to have paid off during the Navy Yard shootings last Monday. The coordination between Metropolitan Police, Capitol Police, FBI and the other first responders made a difficult situation more manageable. Allan Tilles is the chairman of the telecommunications department at the law firm Shulman, Rogers, Gandal, Pordy & Ecker. He talks about what went right and what more we can expect from inter-operability in the future.
