Wait. Double major in something difficult or business or something, or go abroad for a year. I started college at 16, and while I was ready for that, law school is a little different than college. Law schools want emotional maturity. The law profession requires it. And trust me, it sucks to graduate from college and not be able to drink. If you want to go ahead and graduate in two or three years, that's fine, but try and work for a while first. If you can work for a judge or as a legal secretary for a big firm, that will look even better on law school apps. I speak from experience. I graduated in May, turned 21 in September, and I'm taking a year off, working for the state Court of Appeals. I think it's better for me personally (I'm also getting married in December, so I do have some emotional maturity) and professionally (I'm meeting judges I can clerk with during the summers and bulking up my resume). Regardless, wait until your at least 20 or 21 to apply, and take advantage of the opportunities you have as an undergrad (it'll be your last chance to really goof off without having to study too hard).
