View all 31 ReflectionsI just learned of you for the very first time today while watching a rerun of the tv show, “Rescue 9-1-1.” Before today, I had never heard about this tragic event. Police officers risk their lives everyday and I have the utmost respect and admiration for every single one of them. It is very evident that you had a profound impact on those around you as spoken by them on the show. Thank you for making the ultimate sacrifice and for selflessly laying down your own life for your fellow human beings.
