seriously, the guy said criminal justice? i majored in that and that's how i came to the decision to go to law school.
but yeah, i agree with everyone else. don't do a pre-law major, just find something that interests you, be it history or poly sci whatever and major in that.
and i wouldn't stress about it too much just yet. most schools don't make you declare a major until the end of your sophomore year, which gives you 4 full semesters to figure out what you like.
