Correct me if I'm wrong, but I believe that Texas Tech is the only school that offers Forensic Science as a major. So, if you wanted a degree in Forensic Science, you'd have to go to TTU. I think you ought to look at the schools you're interested in and see what majors each has to offer.
Law school adcoms don't really care what you major in (as long as you do well), but they tend to frown upon majors in the performing arts, criminal justice, and photojournalism.
Also, I don't believe that one's major can really help her/his ability to practice in a certain field of law. Granted, a degree in Accounting will be of some benefit for Tax Law; Economics/Business for Corporate Law; and Engineering for IP. However, law school will teach you plenty about Criminal Law; you don't need to try to 'specialize' now. Most people don't know what they want to 'specialize' in when they begin law school/college, and those that think they do tend to change their minds.
If you want to major in Forensic Science because you actually enjoy it (or because you like CSI?), then go for it. But don’t major in it just because you think it will:
- help you get into law school {because it won’t help or hinder}
- help you prepare for law school {because, again, it won’t help or hinder}
- be good prep for the practice of criminal law {because you might change your interests, and even it you don’t: it won’t help or hinder}
