 One major event that took place during Washburn 's tenure was Anthony Burns ' arrest and trial under the terms of the Fugitive Slave Law of 1850 . The case galvanized anti @-@ slavery activists , who protested outside the courthouse and sought both legal and extra @-@ legal remedies to secure Burns ' release . Washburn refused to intercede in the matter , bringing criticism , and Burns remained in custody at the time Washburn left office . Burns was eventually returned to slavery , after which abolitionists purchased his freedom .
