In 1989, a friend of Stone-Manning's, and fellow environmental activist, was involved in tree spiking in Idaho's Clearwater National Forest. At the friend's behest, Stone-Manning wrote an anonymous letter to federal officials, informing them of the tree spiking and warning that "a lot of people could get hurt" if logging were to continue. In her 1993 federal court testimony, Stone-Manning admitted that she had retyped, edited, and mailed the letter. She received prosecutorial immunity in order to testify against the activist. The activist was found guilty and sentenced to 17 months in prison.^[11]
