Ahead of the one-year anniversary of the Boston Marathon bombing, people gathered to pay their respects at the Boston Public Library's memorial, where objects left by mourners were collected for a display of running shoes, hats, notes, and more. President Barack Obama and First Lady Michelle Obama also participated in a memorial this week, touching down in Texas for both a Fort Hood memorial service and the 50th anniversary commemoration of the Civil Rights Act. Across the globe, things were decidedly lighter for Prince William and Kate Middleton, who continued their royal tour adventures with little Prince George. See all that and more with the week's best pictures from around the world!
