Roman Law, and we have been hacked again

Much of how modern legal systems work (particularly Civil law) is derived from the Romans. We have even kept the Latin terminology for many of our legal practices. The following four principles were derived by the Romans and remain an important part of our legal system.
1-All citizens have the right to equal treatment under the law.
2-A person is innocent until proven guilty.
3-The burden of proof rests with the accuser rather that the accused.
4-Any law that is unreasonable or grossly unfair will not be upheld by the court.


 A list of some of the Roman laws can be found here. With the previous link and this link, answer the following questions.
1. Was anyone above the law?
2. Were the laws written fairly, treating everyone equally?
3. How many times can I try and sell my son?
4. What would happen to Weird Al if he lived in Ancient Rome?
5.The right to be judged by your peers the Romans took from which society?
