I did. I didn't do it to get into law school though, I did it to change careers, then I did and now I want to change careers again, and luckily had that second degree.
I guess just make sure you're in a place where you're confident you can do really well in the courses. I would also try to work on the LSAT first because if you go through the second degree but your LSAT continues to hold you back it will be a lot of time and money wasted.
It will be a lot of work and very expensive, and you should be aware that there are schools that do not accept your second degree so you will be limited to a certain number of schools that you can apply to. But if you have the motivation and desire to make the sacrifices for a shot at getting in, it's a way many other applicants have gone about overcoming an initial poor GPA.
If you have any questions I'm happy to try to answer!
