I'll take an elephant for protection. Imagine they could throw their weight around in prison.
Was told an interesting story by my dentist. A guy showed up to see him for dental work without calling in advance. the guy said he wanted his gold teeth removed and would pay what ever the dentist wanted to have the work done that day. Apparently if you have gold teeth, as this guy had, gangs in prison will pull them out for free.
I guess if looking for protection in prison a dentist might be another choice.
