Sister Megan Rice and protesters Michael Walli and Greg Boertje-Obed were convicted Wednesday of sabotaging the plant and damaging federal property last year at the Y-12 National Security Complex in Oak Ridge.
The sabotage charge carries a maximum prison term of up to 20 years. The damaged property charge has a penalty of up to 10 years.
Thapar said that the defendants can’t meet the first requirement as federal prosecutors have said they plan to seek prison time.
Thapar also noted that the defendants have not shown any “unique circumstances that would weigh against detention.”
