President Obama has issued a proclamation directing that the United States flag be flown at half-staff upon all public buildings and grounds, beginning immediately and lasting until sunset on April 20, 2013, as a mark of respect for the victims of violence in Boston, Massachusetts, and for their families and for all those whose lives were forever changed by these senseless acts. In accordance with this proclamation, Arkansas State flags will also fly at half-staff until sunset on Saturday, April 20, 2013.
