CS majors going to law school

I want to go to law school, but I've chosen my undergraduate major to be CS. I genuinely enjoy computer science and want to keep studying it, but I'm afraid that it will be hard for me to get a good GPA (3.8-3.9) as a computer science major, and be at a serious disadvantage to students applying to T14 law schools with humanities major.

I know it's unreasonable to ask for the the best of both worlds, but do you have any advice to people studying CS and wanting to go to law school? Are there people who have managed to reliably keep their GPA up during their undergraduate degree, such that they can attend a T14 school?
