Plainfield teacher and photographer Joel Plummer is an Instagram must-follow if there ever was one (@plummerphotos). Mr. Plummer’s professional photos are largely sports related, while the pictures he shares online also center on family life and the socio-political realm.

On Thursday, Joel Plummer released an ebook of powerful images, video, and commentary about the increased political activism during the past two years in response to state-sponsored violence against black Americans. The movement, which Plainfield View has covered on more than a few occasions, is commonly referred to as #blacklivesmatter.

“The point…is to show the viewer that if you decide to enlist in the fight against oppression, you will not stand as an individual,” says Plummer in its pages, “but rather as part of an army of many thousands who collectively have more than enough power to change the world.”

While the download is free at http://blacklivesmatterbook.com/ for both desktop and mobile devices, those who appreciate his work are asked to lend their influence in return – to share the book with at least one other person.

Check out a few photos below, followed by a promotional video.
