New York CNN —Companies are closing headquarters, scrubbing their websites of top executives’ photographs and increasing armed security details for key leaders following the killing of UnitedHealthcare CEO Brian Thompson. But companies in a wide range of industries are racing to enhance security measures for executives in the wake of the killing. Some are asking for armed security personnel for executives as they travel and commute to work from their homes. Buckner said that in the first several hours following the shooting, 47 companies contacted Global Guardian requesting additional executive security. Buckner said that executives often travel with armed security protection when they go overseas, but such security details have been growing in the United States in recent years.
