Hi David:
I also have marauding hunters roaming my neighborhood, and yet, all my tortoises live outside. As long as you either bring the tortoise in at night, or provide a safe and secure nighttime hiding place, your tortoise will be fine outside. The type of hunters that you've described usually hunt at night. During the day your tortoise will be fine outside. Please reconsider this. Its much cheaper in the long run to let your tortoise be a tortoise, and live outside.
