This month marks the 30th anniversary of the failed assassination attempt on President Ronald Reagan.

On March 30 1981, John Hinckley Jr. opened fire on Reagan's entourage in  Washington, D.C. and  injured the president and three others.

Journalist Del Quentin Wilber has written a book about the events of that day and the aftermath, compiled from over 100 interviews.

Some information about the book, as well as an audio interview, can be found in an article on NPR's website, and here's a link to a book review from The Washington Post.
