[5] In 2000, Platte, along with two other members of her religious congregation, Sisters Jackie Hudson, O.P., and Carol Gilbert, O.P., illegally entered Peterson Air Force Base and sprayed a fighter plane with their own blood.
They wore white jump suits bearing the words "Citizen Weapon Inspection Team", and proceeded to pray in front of the silo as they poured their own blood on it in the shape of a cross.
They continued protesting into their pre-trial hearing; wearing full religious habits, the Sisters answered the judge by nodding without speaking.
At the start of their trial, Robert E. Blackburn, the presiding judge, granted an in limine motion to the prosecutor, which prevented the sisters from arguing that their actions were legal under international law and the Nuremberg defense.
[9] The book Transform Now Plowshares: Megan Rice, Gregory Boertje-Obed, and Michael Walli (Liturgical Press 2022) is dedicated to her, and features many of the antinuclear actions she did with sisters Gilbert, Hudson, and others.
