Miniature American flags line the lawn in front of San Juan Bautista City Hall in commemoration of the Sept. 11, 2001 terrorist attacks on the United States. Twenty-two years ago, terrorists crashed two hijacked passenger planes into the Twin Towers in Manhattan, one into the Pentagon in Arlington, Va., and a fourth into a field in Pennsylvania. The coordinated attacks by Al-Qaeda left 2,977 people dead, and sparked numerous counter-terrorism and safety measures that forever altered life worldwide.
