Is it possible to do a research on both Computer Science and Law, without a Law Degree?

I'm currently a computer scientist, with the work experience in both Academia and industry. I'm starting to get very interested in the intersection of law and computer science. I do think we really need people that know law and computer science at the same time very well, to decide on the important issues currently we are dealing with.

What is the best way for me to deal with my decision? Do I need a law degree first, before I do research on this matter, If so I should start with an Bsc?; Or should I apply for a junior research position in the law department?
