Q. Why did you write Stop the Killing?
We need to be as devoted as we were after 9/11 to watch out for each other, and when we see behaviors of concern or hear leakage from a person on a pathway to commit a mass shooting, we need to say something.
Q. Can we stop the killings?
Probably the biggest misunderstanding about gun violence events is there's going to be enough time in the heat of the moment to make a decision about what to do or even to tell other people what to do.
Q. Do we learn anything good from these terrible shootings?
With the FBI, I worked the Holocaust Memorial Museum shooting in Washington DC and the Pentagon shooting in Virginia several years ago. I worked many more while running the active shooter program in FBI headquarters as part of the team coordinating responses from the FBI's Strategic Operations Command Center.
