Martha Stewart says she'd do okay in prison because she's been camping and slept on the ground. I have no firsthand knowledge of prison conditions but it seems like they actually give you beds. No need to sleep on the ground. I think the bad part about prison is the restriction of your freedom. Something you're not likely to experience on a camping trip.
Martha also compares herself to Nelson Mandela and seems to be saying that she didn't get a fair trial. It was a lot easier to feel sorry for this multi-millionaire before she opened her mouth.
