The lasy response, beyond being unnecessarily rude, is also wrong. Putting aside the author's subjective judgment that none of the schools listed were "good"---despite everyone's almost religious reverence regarding the U.S. News and World Report rating system [my law school ranks in the first tier, so this is not sour grapes], it is not the only or best way to evaluate legal education---a GPA of 2.9, if obtained years ago before grade inflation was fashionable, is probably worth a modern day 3.3, which is competitive at many law schools. Of course, one needs to know more about the undergraduate institution involved, the major of the student, and the classes taken in and outside the major, before judging a GPA. A 3.0 im some majors, at some law schools, says a lot more about potential law school ability than a 3.8 in another major at another institution.
I would also disagree with the claim made by "Pat Man" who is seemingly unhappy with his outcome (although SUNY Buffalo is, in my view, a very good school, especially for those who have an interest in interdisciplinary education)---the admissions process is not random. This is not to say that the process is perfect, for as with all institutions run by humans, it is far from that. But, as I just noted, you can't simply take a "low" or "high" GPA at face value. LSAT is a bit more useful, although it is subject to attack on various grounds, some of which may be justified.
The process necessarily requires individualization, to the extent possible (which is hard if a law school receives thousands of applications), to try to determine whether the individual shows promise (and more or less promise than another aopplicant), and whether the individual's intellectual background will add to the classroom dynamics.
Is this admissions process foolproof? No. Is it done by some scientific, entirely neutral method. No, and few of us would want that approach in selecting persons who must work in the law and society. Is it subjective? Yes, in part. Is it perfect? By definition, when there is subjectivity there will not be perfection, unless one agrees with the subjective conclusions reached. But, is it random? Hardly.
