'AMERICA IS WEEPING': TAKING STOCK AFTER 3 DAYS OF TRAGEDY

This week's killings come in the midst of a divisive presidential election, amid fears of terrorism and on the heels of the latest mass shooting that claimed 49 innocent lives. The killings in Dallas happened just blocks from the book depository where another sniper took aim at President John F. Kennedy. It ended his life and a period of American history that became regarded as "Camelot," and became a presage to the strife, unrest and other assassinations that followed.
