The question is at first, why she went to prison. This can already be a deciding factor in what rights or lack thereof she'd have. What are the rules in general about privileges in prison. Do they also count for other inmates? If other inmates have that right too, so should celebrities have. I mean the meme doesn't tell all that. I don't think celebrities should have more rights than others simply because they are celebrities, but at the same time they should also not have less rights than non-celebrities.

Clyde Barrow, from the famous duo Bonnie & Clyde is said to have become a very violent person due to the horrors he experienced in prison. If that's true, prison had the OPPOSITE effect on him than it should have. After all, we want prison to make sure people get out of it better than they came in and never do it again.

Every person is different and the same goes for people in prison.
